Intellicast Merges with Weather Underground

Starting January 17, 2019, we began redirecting traffic from Intellicast.com to wunderground.com. Even though the Intellicast name and website will be going away, the technology and features that you have come to rely on will continue to live on wunderground.com.

The radar emits a burst of energy (green in the animated image). If the energy strikes an object (rain drop, snowflake, hail, bug, bird, etc), the energy is scattered in all directions (blue). Note: it's a small fraction of the emitted energy that is scattered directly back toward the radar.

The National Weather Service's 148 WSR-88D Doppler radars can detect most precipitation within approximately 90 mi of the radar, and intense rain or snow within approximately 155 mi. However, light rain, light snow, or drizzle from shallow cloud weather systems are not necessarily detected.

Weather radar (also known as Doppler weather radar) is an instrument that sends pulses of electromagnetic energy into the atmosphere to find precipitation, determine its motion and intensity, and identify the precipitation type such as rain, snow or hail.

The WSR-88D is one of the most powerful and advanced Weather Surveillance Doppler Radar in the world. Since first being built and tested in 1988, it has been installed and used operationally at over 160 locations across the United States, including Alaska and Hawaii.

Weather Underground will discontinue the webcam hosting service effective October 21, 2021 in order to better focus on the core products that make Weather Underground one of the best destinations for weather enthusiasts.

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.

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).

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.

LiDAR has higher resolution and can provide more detailed and accurate measurements than radar.

What's more accurate, AccuWeather or weather Channel? ›

The study analyzed 120 million forecasts from over 1,000 locations globally over a four-year period ending December 31, 2018, and AccuWeather was found to be the clear winner as the most accurate provider of weather forecasts in temperature, precipitation and wind speed– a clean sweep of all categories -- for a 1-5 ...

This comprehensive test analyzed over 25 million weather forecasts in more than 1,000 locations globally, and AccuWeather was the clear winner in high- and low-temperature forecasts, proving to have the lowest average absolute error and the greatest percentage of forecast accuracy within 3 degrees F.

Blue and green colors represent light-to-moderate rainfall. Yellow and orange colors show moderate-to-heavy precipitation, while red is very heavy rainfall and pink and blue colors inside the red color represent hail of different sizes.

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.

A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

As the beam travels away from the radar source, it gets higher above the ground due to the curvature of the Earth. Therefore, if the precipitation is restricted to very low levels, especially within a few hundred feet from the ground, the radar beam might overshoot it, leading to undetected rainfall.

Military Radar systems work in a wide band of transmitted frequencies. The higher the frequency of a radar system, the more it is affected by weather conditions such as rain or clouds. But the higher the transmitted frequency, the better is the accuracy of the radar system. Absolutely, yes.

Final answer: Doppler radar provides the key advantage of determining an object's velocity or speed relative to the radar's position, which conventional radar systems cannot do. Consequently, Doppler radar is crucial for improved weather forecasting and safety measures.

On July 2, 2012, The Weather Channel announced that it would acquire Weather Underground, which would become operated as part of The Weather Channel Companies, LLC, which was later renamed "The Weather Company".
