Who has the best weather radar maps? ›

These droplets might be too small for the radar to detect effectively. Since low-level moisture can lead to the formation of such fine droplets, the rain might be falling right under our noses but stay invisible to the radar.

The radar's computers measure the phase change of the reflected pulse of energy which then convert that change to a velocity of the object, either toward or from the radar. Information on the movement of objects either toward or away from the radar can be used to estimate the speed of the wind.

Red shows winds blowing away from the radar, and green shows winds blowing toward it. Stronger winds usually equate to brighter colors on the radar imagery. You can spot rotation and a possible tornado in a thunderstorm by looking for strong winds blowing in different directions right next to each other.

Clime: NOAA Weather Radar

With a Clime paid subscription, you get one of the most comprehensive weather radars out of all the weather apps on this list.

According to ForecastWatch, the premier organization for evaluating the accuracy of weather forecasts, The Weather Company is more likely to be the most accurate across all geographic regions studied (U.S., Canada, Central America, South America, Europe, Africa, Middle East and Asia-Pacific) and time periods covered.

Here's the one from NOAA that shows colors for different rain intensities in inches per hour: As you can see, purple represents the highest intensity, 16+ inches (400+ mm) per hour. NOAA does not use black in its scale. If a point on the radar map is black, no precipitation is falling there.

Red. Time to break out the rain boots! Red on the radar is associated with torrential downpours. Windshield wipers can't keep up, making it hard to see as rain is falling at rates over 2 inches per hour.

Yes, police can use radar in the rain. However, certain factors can affect the accuracy and efficiency of radar systems during bad weather. Our findings show that, while radar systems are robust, heavy rain can reduce their range.

On a weather radar map, a tornado is usually indicated by a smaller area of red surrounded by a larger area of green. However, modern radar systems can also indicate debris balls, a sign of a tornado on the ground.

What is the 1 in 60 rule weather radar? ›

Radar Beam Exercise

When navigating using VOR's, they used the 1-In-60 rule (i.e. if an aircraft is 60nm from a VOR and 1° off-track, the aircraft is 1nm off-track). But there is a more generic form of the rule that is useful for radar. Just take the radar range and add two zeros to find out what one degree equals.

dBZ. Nondimensional "unit" of radar reflectivity which represents a logarithmic power ratio (in decibels, or dB) with respect to radar reflectivity factor, Z. The value of Z is a function of the amount of radar beam energy that is backscattered by a target and detected as a signal (or echo).

Purple indicates “range folding”— where the radar cannot determine the radial velocity. Velocity image of a large-scale weather system. denotes the approx. location of the radar.

The colors are typically a spectrum. The greens indicate light or moderate rainfall. Yellow, orange, and red indicate moderate to heavy rainfall and can also indicate hail. Whites or blues mean snowfall and pink indicates freezing rain, sleet, or a wintry mix.

Light green: light rain, or light rain aloft not reaching ground. Dark green: light to moderate rain. Yellow: moderate rain. Orange: heavy rain. Red: very heavy rain or rain and hail.

IBM's The Weather Company Continues to Be the World's Most Accurate Forecaster Overall, Despite Growing Competition and Amid Weather's Increased Impact. - The Weather Company was over 3 times more likely to be the most accurate forecaster than other weather providers studied.

A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.

RadarScope is an app for your phone that brings live NWS radar to the palm of your hands. Most radar apps process the data on a server before pushing a jpeg or gif image to their app. RadarScope uses raw data processed on your phone. This means you see the data almost as fast as NWS forecasters see the data.

Tools such as surface maps and upper-level maps provide basic weather information, while satellite images and radar can track storms and systems. Thermodynamic images can also provide information about pressure and temperature changes throughout the atmosphere.
