The weather radar (11) further comprises an antenna movably mounted on the mechanical support and rotatable about an axis of rotation OX. The antenna comprises a base on which is arranged at least one fin (16) which extends radially along the axis of rotation OX. The fin has a free face...
On stormy nights, the meteorologist will interrupt regular programming. He will always say that Doppler radar indicated rotation in a certain area. He is quick to point out that just because Doppler radar picked up on rotation, this doesn't mean an actual tornado is on the ground. It does ...
(RADAR= Radio Detection and Ranging). Radiation Energy emitted in the form of electromagnetic waves. Radiation has differing characteristics depending upon the wavelength. Radiation from the Sun has a short wavelength (ultra-violet) while energy re-radiated from the Earth's surface and the ...
You can see on this radar image the hook echo in the top left, with rotation that had been there for a couple of scans. This storm was rotating and producing large hail at this time. The radar was picking up winds as high as 64 knots, which is ~73 mph! The green colors on the ...
The following topics are discussed: Radar analysis of Hurricane Esther 1961, Crossing angles in hurricane bands, and Origin of a tornado's rotation. A complete list of other reports with abstracts, published in connection with this research, is included. 关键词: METEOROLOGICAL RADAR STORMS WEATHER...
Storm characteristics on the radar include arrows showing the direction of motion and icons indicating the position and amount of hail, mesocyclones, and tornadic vortex signatures that indicate the existence of rotation in supercells and potential tornadoes. ...

Doppler Radar gives forecasters the capability of providing early detection of severe thunderstorms that may bring strong damaging winds, large hail, heavy rain, and possibly tornadoes. Combined with satellites, radar gives forecasters the ultimate tools to provide accurate forecasts and advanced severe...
And according to the National Weather Service, radar indicated rotation. Numerous severe thunderstorm warnings were issued earlier for counties in and around Metro Detroit. Winds had been expected in excess of 60 miles per hour with pea-size hail. Lows tonight will bottom out in the ...
The weather radar observation indicated that the rainband was maintained for 11h. The maximum length and width of the rainband observed in 1999 was ~200km and ~20km, respectively. The rainband observed in 2002 was not so developed compared with the case in 1999. The Froude number averaged ...
