Got radar? You do now: Grab your mobile device and head to. Be sure to check out these video tutorials and frequently asked questions to help you get started using the site. We added new features to the radar viewer based on feedback we received from the public and emergency management community. The webpage is more reliable now that it's on an operationally supported system 24/7. Base Reflectivity Doppler Radar loop for West TN, providing current animated map of storm severity from precipitation levels. The new page’s infrastructure allows for easy integration of new datasets, like satellite imagery, in the future and Radar animation loops can be saved, shared and used on social media For times when a single radar is out of service, you still have coverage since radar beams overlap Ībility to customize data to any domain, and data layer preferences can be saved or bookmarked More radar data, including 159 NEXRAD Doppler radars and 45 Terminal Doppler Weather Radars. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. Soc., Boston, 1978).The radar webpage can be saved on your mobile device home screen just like an app, so you can use this powerful weather monitoring tool on the go.Īccess to certain dual-polarization radar products to help differentiate between precipitation types, such as rain and snow Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. 76–2 (Alberta Research Council, 1976).īrowning, K. Here we describe an objective use of radar reflectivity factor data from a single conventional weather radar to give information related to the three-dimensional motions within a storm.īrowning, K. Pattern recognition schemes using correlation coefficient techniques 6, Fourier analysis 7, and gaussian curve fitting 8 have been used with radar and satellite data, but primarily for detecting overall storm motions, echo merging and echo splitting. Because of the inherent advantage of Doppler radar in motion detection, little effort has been directed toward developing objective schemes of determining internal storm motions with conventional meteorological radars. Two 4 or three 5 Doppler radars collecting data in conjunction, the equation of mass continuity, and an empirical radar reflectivity–terminal velocity relationship have enabled the estimation of the full three-dimensional airflow fields in parts of storms. Doppler radar added a new dimension to our capabilities through its ability to measure directly the radial component of motion of an ensemble of hydrometeor particles. This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. Check Spectrum Bay News 9s Klystron 9 Interactive Radar to get detailed, street-level conditions for the Tampa Bay area. The first type of data currently available is reflectivity. Both Barge and Bergwall 2 and Browning and Foote 3 have used fine scale reflectivity structure to determine airflow in hailstorms. Use radar data with caution especially if your area of interest is far from the nearest radar location We currently have two types of radar data available with plans to add more soon. This is called radial velocity as it is the component of the targets motion that is along the direction of the radar beam. However, the only motion it can 'see' is either directly toward or away from the radar. Such approaches have continued by using the increasingly finer scale details provided by more modern radar systems. One of the best features on the 88d Doppler radar is its ability to detect motion. Early users of radar gave total storm movement only, whereas later radar data were used to reveal internal motions based on information related to cloud physics such as the three-dimensional morphology of the storm volume. Radar has long provided information on the three-dimensional structure of storms from measurements of the radar reflectivity factor alone. A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. KNOWLEDGE of the kinematic structure of storms is important for understanding the internal physical processes.
