Wind observations with Doppler weather radar
Introduction Weather radars are commonly employed for detection and ranging of precipitation, but radars with Doppler capability can also provide detailed information on the wind associated with (severe) weather phenomena. The Royal Netherlands Meteorological Institute (KNMI) operates two identical C-band (5.6 Ghz) Doppler weather radars. One radar is located in De Bilt and the other one is loc...
متن کاملMST Radar Observations of Gravity Waves and Turbulence near Thunderstorms
The effect of deep convection on the intensities of gravity waves and turbulence during the summer at White Sands, New Mexico, is investigated using 50-MHz mesosphere–stratosphere–troposphere (MST) radar observations and surface weather reports. Radar data taken at 3-min intervals from the summers of 1991 through 1996 (with occasional gaps of varying length) are used to construct hourly means, ...
متن کاملEffects of Anomalous Propagation Conditions on Weather Radar Observations
The effect of atmospheric propagation on radar observations is an important topic both for radar application developers and end-users of radar products, particularly of weather radar systems. An excellent review of this subject is given by Patterson (2008), and most general books about weather radars have a chapter on the topic –see for example Battan (1973), Collier (1996), Doviak and Zrnic (2...
متن کاملA Pulse Compression Waveform for Improved-Sensitivity Weather Radar Observations
The progression of phased array weather observations, research, and planning over the past decade has led to significant advances in development efforts for future weather radar technologies. However, numerous challenges still remain for large-scale deployment. The eventual goal for phased array weather radar technology includes the use of active arrays, where each element would have its own tr...
متن کاملModification of the relaxed eddy accumulation technique to maximize measured scalar mixing ratio differences in updrafts and downdrafts
A modification to the relaxed eddy accumulation (REA) flux measurement technique is proposed which maximizes the scalar mixing ratio difference in updrafts and downdrafts. This technique was developed with the goal of measuring the stable isotope (C/C and O/O) ratios of updraft and downdraft air and thus the net fluxes of CO2 and COO. Current mass spectrometer precision is small relative to mea...
