In addition to the free features of the app, additional upgrades are available, including real-time hurricane tracking - great for the start of hurricane season. A new feature introduced in this version of MyRadar includes the ability to receive alerts based off of Tropical Storm and Hurricane activity you can configure the app to send you an alert any time a tropical storm or hurricane forms, or is upgraded or downgraded. MyRadar also has the ability to send weather and environmental alerts, including alerts from the National Weather Service, such as Tornado and Severe Weather alerts. In addition to the live radar, MyRadar has an ever-increasing list of weather and environmentally-related data layers that you can overlay on top of the map our animated winds layer shows a breathtaking visual representation of both surface winds and winds at the jetstream level the frontal boundaries layer shows high and low pressure systems as well as frontal boundaries themselves the earthquakes layer is a great way to stay on top of the latest reports on seismic activity, completely customizable as to severity and time our hurricane layer allows users to stay on top of the latest tropical storm and hurricane activity throughout the world the aviation layer overlays AIRMETs, SIGMETs and other aviation-related data, including the ability to track flights and display their IFR flight plans and paths, and the "wildfires" layer allows users to stay abreast of the latest fire activity around the United States. These alerts can be a life saver when you're on-the-go and don't always have time to check the weather - our systems will proactively do the work for you and let you know in advance before the rain hits. Instead of having to check the app all the time, MyRadar will send you an alert up to an hour in advance as to when the rain will arrive at your current location, down to the minute, including details on intensity and duration. One of the most useful features in MyRadar is the ability to provide advanced rain alerts our patent-pending process for predicting hyper-local rainfall is the most accurate in the industry. Check your phone and get an instant assessment of the weather that will impact your day. This basic functionality provides the quickest way to get a snapshot of the weather on-the-go, and it's what has made MyRadar so successful over the years. Just start the app your location pops up with animated live radar, with radar loop lengths of up to two hours. MyRadar is a fast, powerful, easy-to-use weather app that displays animated weather radar around your current location and to quickly show what weather is coming your way. These scans are interpreted by a computer and translated into an image.Thanks to everyone for making MyRadar so successful, with over 50 million downloads! A complete set of scans takes around 5 minutes to complete.
Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second.
Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. The radar instrument receives a signal from this reflected energy during its listening period. A small fraction of the scattered energy is directed back toward the radar. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions.
The radar emits a burst, or pulse, of energy.
NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy.
