According to Reed Timmer, a famous US storm chaser, Tornado Alley is expected to expand into 3 more states in 2024. Because of climate change and the consistently high temperatures in the Gulf of Mexico, there’s often enough moisture for storm systems throughout the year, including winter. This could lead to an increase in tornadoes even beyond the typical season. Timmer thinks that these climate shifts are causing Tornado Alley to grow, moving it further south and east into Louisiana, Florida, and Texas.

Tornadoes are nature’s formidable force that can wreak havoc and instill fear in the hearts of those in their path. To understand and mitigate the impact of these swirling tempests, scientists use various metrics to define their intensity and characteristics. In this article, we will delve into the methodologies and instruments used for the measurement of these powerful atmospheric phenomena. But first, let’s refresh the general tornado knowledge.

What Is a Tornado and How Does It Form?

A tornado is a strong vortex that forms during hot weather under a well-developed cumulus cloud. It then spreads to the earth or water body in the form of a giant dark rotating column or funnel. The vortex has a vertical axis of rotation that can slightly incline to the horizon. The height of a tornado may reach hundreds of feet, in some cases up to 1 mile. The diameter may be 30 to 100 ft (10-30 m).

How Clouds Form and Their Types | RainViewer Blog

Mon, 05 Jun 2023 00:00:00 +0000

Clouds are an important aspect of daily weather patterns. They not only add beauty to the sky but also have a significant impact on the weather. A cloud can take many forms, from harmless sugar candy to a death-carrying monster, e.g. a tornado . In this article, we’re going to discuss how clouds form in the sky as well as explore various types of clouds and their characteristics.

How Clouds Are Formed

A cloud consists of water droplets that warm air has lifted from the Earth’s surface. Because the upper atmosphere is much colder than the lower one, the air there cools down rather quickly. The steam condenses and generates tiny particles of water and ice, which form white clouds. Therefore, we can say that every cloud is a kind of atmospheric moisture generator, through which water passes.

What is a front - meaning and different types of front? | RainViewer Blog

Wed, 15 Mar 2023 00:00:00 +0000

When listening to a weather forecast on the radio or TV, you may often hear that a weather front may cause low air temperature, precipitation, or strong winds. But what is a front, how does it form, and what are the types of fronts? Let’s find out in this article.

History of Weather Fronts

At the beginning of the 20th century, the school of Norwegian scientists introduced the concepts of “air mass”, “front”, “cyclone”, and “anticyclone” in weather forecasting. The need for more accurate forecasts was due to historical events, specifically World War I, when the military began using aircraft. Then Norwegian weather forecasters were actively studying the structure of the atmosphere and dangerous natural phenomena associated with it. As a result, they discovered such “synoptic objects” as air masses and weather fronts, whose movement is closely related to atmospheric vortices, high and low pressure zones, cyclones, and anticyclones.

What is the difference between a typhoon, cyclone, and hurricane? | RainViewer Blog

Mon, 06 Mar 2023 00:00:00 +0000

Hurricanes and typhoons are components of a tropical cyclone - a huge mass of clouds that gathers in the sky, rotating counterclockwise at low pressure. Subsequently, it collects moisture, increasing in size. At the center of a cyclone, there is a circular area called an eye. The weather in this area is relatively calm. The eye is surrounded by an eye wall - a ring of thunderstorms with strong winds and the most severe weather conditions.

A tornado is an atmospheric vortex that occurs in rain or thunderclouds. It looks like a cloudy funnel, which often descends to the ground level. Tornadoes spread at high speed and can cause significant damage. For most of them, the wind speed does not exceed 100 miles per hour. However, some whirlwinds can move at speeds up to 300 miles per hour.

Tornadoes occur on all continents of the planet, but most often they happen in North America, especially in the United States. The US suffers tornadoes of greater intensity than any other country, meaning that the deadliest tornadoes happen here. It is the only location in the world where these weather events are ranked as violent - between EF4 and EF5 according to the enhanced Fujita Scale:

Thu, 22 Dec 2022 00:00:00 +0000

RainViewer 2.19 for iOS presents a new notification center, where you can customize weather alerts for each of your saved locations and decide which notifications to receive. You no longer need to open Settings and look for the Notifications section, as we’ve moved these settings to the new Notification Center on the app’s main screen. Now you can quickly and easily set up weather alerts.

In this release, we’ve added two new types of notifications - Severe Weather Alerts and Tropical Storms. In total, the RainViewer app now has the following notification types:

What does a tornado look like on radar and how to spot a tornadoes on maps? | RainViewer Blog

Wed, 21 Dec 2022 00:00:00 +0000

A tornado is an extremely dangerous natural phenomenon that causes destruction, injury, and often death. Most tornadoes occur in the United States, with the tornado season lasting from March to July. According to the National Weather Service, about 80 people die because of tornadoes each year in the US. The most dangerous region concerning tornadoes is called Tornado Alley and includes several states, specifically, Texas, Oklahoma, Kansas, and Nebraska.

Let’s take a look at the most damaging tornado events in US history:

2021 Atlantic Hurricane Season - how was it? All Facts from RainViewer Team

Tue, 13 Dec 2022 00:00:00 +0000

The 2021 Atlantic hurricane season was so rich in storm events that the World Meteorological Organization ran out of storm names. In May 2021, NOAA predicted 13 to 20 named storms with 3 to 5 major hurricanes. In total, 21 storms of different categories were raging over the Atlantic Ocean, making 2021 a record-breaking year. More hurricanes took place only in 2005 (27) and in 2020 (30).

It was also the most expensive hurricane season, causing damage worth $67 billion. 8 hurricanes made landfall in 2021, and 3 of them cost the affected countries billions of dollars.

Are tornadoes increasing in frequency in 2022? - Average annual and monthly numbers of tornadoes in the world | RainViewer Blog

Thu, 08 Dec 2022 00:00:00 +0000

Every year in late spring and summer the combination of hot weather and powerful thunderclouds leads to the formation of funnel-shaped air disturbances, commonly known as tornadoes. Looking like vertical or slightly inclined vortices, sometimes they are also called twisters - a slang name for a tornado.

During a tornado, cold air from high layers of the atmosphere descends. A funnel consisting of water vapor and air - the “trunk of a tornado” - stretches from a thundercloud to the ground. A violently rotating column of air with a diameter of several hundred meters rushes over land at wind speeds of 30 to 60 miles per hour, destroying everything that comes in its way.

Black Friday Around the World

Thu, 03 Nov 2022 00:00:00 +0000

November is all about the shopping season and the biggest revenue of the year for product companies. Highly promoted Black Friday and Cyber Mondays sales started in the US in mid-2020. During the last 20 years, they’ve got a massive spread and become popular all over the world.

The holiday season is a great time to localize and promote your business in different countries. However, while some countries use the same etymology, others prefer their own name for the ‘Black Friday’ sale and might even be dated because of historical or traditional influence.

RainViewer Lock Screen Widgets are ready for iOS 16

Mon, 12 Sep 2022 00:00:00 +0000

Apple starts to roll out the iOS 16 update gradually, introducing all kinds of Lock Screen personalization to the iPhone end users. The customization should result in a unique Lock Screen. You can choose widgets, customize colors as well as use emojis, photos, or built-in wallpapers.

RainViewer is one of a few apps that has released an iOS 16-ready update allowing its customers to be in trend. Our Lock Screen Widgets are ready to be set up on iPhone to get the latest weather updates at a glance on the Lock Screen.

RainViewer adds National Weather Service alerts

Tue, 06 Sep 2022 00:00:00 +0000

RainViewer 2.17 for iOS and Android adds the ability to receive severe weather alerts issued from the National Weather Service (NWS). These alerts notify people of severe weather conditions in communities across the United States and its territories.

NWS alerts can notify you of tornadoes, fires, extreme heat, and potential flooding, among other events. Professional forecasters at the NWS consider a variety of sources and data before they issue a warning. In every case, they attempt to issue the warning as far in advance of expected hazardous conditions as possible. Extreme heat, for example, might be predicted many hours in advance, while a tornado warning might be issued a matter of minutes before an anticipated event.

Tue, 14 Jun 2022 00:00:00 +0000

The weather app you’ll want on your wrist

The latest RainViewer update delivers several enhancements for people who use RainViewer on an Apple Watch. It’s a huge improvement that can make the RainViewer Apple Watch app the only weather app you need on your wrist.

Display radar on your wrist

#StandWithUkraine

Wed, 25 May 2022 00:00:00 +0000

RainViewer is a Ukrainian Project 🇺🇦

Part of our Team is in Ukraine now, under fire, sheltering from Russian missiles and numerous bombards. We continue working and developing our project, despite the war. We cannot guarantee the timely updates of our app, responses to technical requests, or bug fixes. Thank you in advance for your understanding!

Changes in our project:

RainViewer no longer displays any Russian and Belarusian radars. Radar maps and forecasts are no longer available for these countries.

Beautiful RainViewer weather widgets on Android

Thu, 19 May 2022 00:00:00 +0000

RainViewer 2.16 on Android brings you more adaptable widgets than ever before. (To learn the basics of how to install and customize widgets, read How to Use RainViewer Widgets on Android and iOS. In every case, once your widget is installed, tap and hold on the widget, then tap the pencil icon to access widget options.)

The RainViewer Android app widgets include:

a minute-by-minute precipitation forecast widget, which displays an hourly forecast when it’s not raining,
a current conditions widget with a forecast for the next few hours,
an hourly forecast widget, which displays a minute-by-minute forecast when it’s raining,
a 7-day forecast, and, of course,
the RainViewer weather radar map.

You may install and resize these widgets on any Android home screen.

Storm Tracking: Now Available in RainViewer 2.11

Sun, 10 Oct 2021 00:00:00 +0000

RainViewer now includes a hurricane tracker to help you track hurricanes, typhoons, and tropical cyclones. Even better, the feature is free for everyone who uses the RainViewer app on either Android or iOS.

Tropical cyclones-commonly called hurricanes in the Atlantic Ocean, typhoons in the Western Pacific Ocean, or cyclones in the Indian Ocean-can disrupt ship and plane routes, and also can cause problems whenever they encounter human-populated places. For example, Hurricane Ida caused significant damage across several U.S. states, from Louisiana, where it made landfall, all the way to the Northeast, where it caused flooding. Some estimates have attributed more than 110 deaths linked to Hurricane Ida, along with more than $50 billion of damages. Tropical cyclones, hurricanes, and typhoons occur over warm waters as the rotation of the earth, warmth of the water and air interact. (See How tropical storms start for more details.)

Precipitation Direction: Where Is the Storm Going

Fri, 09 Jul 2021 00:00:00 +0000

Precipitation direction arrows show you the path of a storm in the Android and iOS RainViewer apps. These arrows are available as a new Premium Feature in the version of RainViewer you can download from Google Play or the App Store as of early July 2021.

One way to get a sense of storm direction is to play recent radar sequences in RainViewer. In settings, select past (or past + forecast) and also choose how much history to show: 1, 2, 3, 6, 24, or 48 hours. Then tap the play button to show the sequence of any rain detected by radar. The loop of images lets you gauge how a storm evolves over time.

RainViewer on iPad: Radar, Weather, and Widgets

Fri, 23 Apr 2021 00:00:00 +0000

Apple doesn’t provide people with a built-in weather app on iPadOS. And even if you do discover Apple’s somewhat hidden weather widget, it doesn’t display radar. RainViewer can serve as your iPad weather app.

Unlike some weather apps, RainViewer doesn’t use satellite data or forecast models to guess where it will rain. Instead, it displays precipitation as detected by active radar data. Since RainViewer shows radar for more than 1,000 sites, much of the world is covered!

Looking for RADAR? RainViewer and Alternatives

Tue, 20 Apr 2021 00:00:00 +0000

If, like us, you’re a fan of radar, there are several other options you can turn to for radar. The following are a few of our favorite sources for radar data, along with reasons we think the sources are useful and the features interesting.

World Meteorological Organization members: official sources

For most people, the first place to look for radar sources should be your country’s official meteorological organization. The World Meteorological Organization maintains a map that lets you click (or tap) on a portion of the world, select a country name from a list, then click through to an official website. From there, you can explore any radar data offered.

How to Use RainViewer Widgets on Android and iOS

Wed, 24 Feb 2021 00:00:00 +0000

RainViewer widgets deliver data at a glance: Unlock your phone, then look at the screen.

With two types of widgets available, RainViewer can show you a recent radar map as well as near-term temperatures and conditions.

Want more info? Tap on the widget to open the RainViewer app.

If you frequently check the weather, we suggest you add both a weather map widget and forecast widget to your phone. The combination of widgets gives you a good overview of current and expected weather conditions. The steps below should help you get started.

RainViewer Released Weather Widgets With Radar Map

Tue, 03 Nov 2020 00:00:00 +0000

A new version of RainViewer 2.2 for iPhone is out with the main focus on the Weather Widget, which is available for iOS 14 users: https://apps.apple.com/app/apple-store/id980123924

RainViewer 2 Isn’t Dark Sky - and That’s Good!

Sat, 01 Aug 2020 00:00:00 +0000

For several years, Dark Sky offered precipitation alerts and short-term forecasts on iPhone, iPad, Apple Watch, and Android devices. But, as avid weather app watchers already know, Apple acquired Dark Sky. As a result, Apple chose to end access to the Dark Sky Android app and Dark Sky website - and has already closed the Dark Sky API for new developer access.

RainViewer Pricing

Tue, 30 Jun 2020 00:00:00 +0000

With RainViewer 2.0 we’re not only changing features, we’re also changing the business model. That means a move to subscription pricing.

Welcome to RainViewer 2!

Tue, 30 Jun 2020 00:00:00 +0000

RainViewer 2 shows you the future - in the form of forecast radar, forecast conditions, and forecast precipitation alerts. These features build on RainViewer’s history of delivering access to radar from more than 1,000 radar sites in more than 90 countries. The redesigned RainViewer app, available for both Android and Apple devices (including iPad, iPhone, and Apple Watch), makes it easier than ever to view past, present, and future radar around the world.

Share Rain Radar Animation

Thu, 16 Jan 2020 00:00:00 +0000

One of RainViewer’s useful tools is the ability to export and share radar animation. In other words, you can export the motion of precipitation (rain or snow) shown on the map as a .gif or .mp4 file. After the export, you can save the animation locally on the smartphone. You can also share it via messengers or on social media to notify friends and followers about the upcoming rain, snow, or any other storm. If you’re blogging and need to illustrate a storm, hail, or heavy rain in your blog post, radar animation would be the best option for this.

Contribute to RainViewer API

Wed, 11 Dec 2019 00:00:00 +0000

RainViewer started as a small project and grew out into a service that provides a single map with over 1000 weather radars. All the data coming from the radars, RainViewer displays on the map: rain and snow animation, precipitation intensity, storm path. This makes it super convenient to observe and monitor doppler radar animations over the world. RainViewer map has the biggest radar coverage in the market, which means you won’t find a map with over 1000 rain radars in open access.

Rain on the Map, But Not Outside?

Mon, 18 Nov 2019 00:00:00 +0000

Radar sometimes detects things that aren’t rain. Bats, birds, and bugs sometimes fly in such numbers that modern radar systems detect the reflections from these creatures. Non-biological things, such as wind turbines in wind farms, also sometimes cause radar to register returned signals.

How Tropical Storms Start

Tue, 29 Oct 2019 00:00:00 +0000

Big storms start small. Tropical cyclone Idai in the Indian Ocean, typhoon Hagibis in the Pacific Ocean, and hurricane Dorian in the Atlantic Ocean all gained energy and organization over time. And while the words vary (e.g., typhoon, hurricane), the term tropical cyclones refers generally to these powerful systems that form over warm ocean water.

Tools You Can Use to "See" More Details About a Storm

Tue, 24 Sep 2019 00:00:00 +0000

When hurricanes and other dangerous weather events happen, weather forecasters warn people of the potential danger. Fortunately, we also have access to many of the images and data that meteorologists, public officials, and emergency managers rely on to make decisions.
