The use of QuikSCAT data for wind retrievals of tropical cyclones is described. The evidence of QuikSCAT 0 dependence on wind direction for 30-m/s wind speeds is presented. The QuikSCAT 0 show a peak-to-peak wind direction modulation of 1 dB at 35-m/s wind speed, and the amplitude of modulation decreases with increasing wind speed. The decreasing directional sensitivity to wind speed agrees wel...

The demand for high capacity data communication is increasing continuously and rapidly. More Network-based multimedia applications such as Internet protocol Television (IPTV), video on demand (VoD), voice over Internet protocol (VoIP), and other broadband services are emerging. Due to congestion in the lower frequency bands many of the services may use millimeter wavelength bands. A good unders...

How much precipitation is contributed by warm rain systems over the tropics? What is the typical size, intensity, and echo top of warm rain events observed by the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar over different regions of the tropics? What proportion of warm raining areas is actually attached to the edges of cold systems? Are there mesoscale warm raining systems, a...
