Millimeter wave radar signals depending on backscattering characteristics of particles and particles size distribution can be used to inverse the microphysical parameters of clouds, but ice clouds are composed of non-spherical ice crystals, so various factors of impacting on the scattering from non-spherical particles must be considered. However, there are few papers that account for the influence...
From Nov. 09 to Nov. 12, 2009, a large range of rain and snow process with low-temperature occurred in North China (named “0911” Blizzard in North China hereafter), it caused severe disasters and losses in the region. The purpose of this paper is to explore the mechanism of the process by analyzing atmospheric conditions. The results show that the warm stratus provided favorable conditions for this...
Typhoon cloud phase has been analyzed with MODIS remote sensing data and atmospheric soundings data. The purpose is to understand the relationship among the temperature, humidity and cloud phase on cloud top, and to find the structure evolution information ahead of precipitation.
Millimeter wave radar has a unique advantage on detecting cloud microphysical structure. However, it is easy to cause the velocity aliasing due to its short wavelength. Velocity dealiasing is an effective means of detecting wind field information with Doppler radar. This paper reviews the cause of velocity folding and proposed a human-machine interaction method aimed at millimeter wave radar in the...
The stationary meteorology satellite data are useful for rainstorm forecasting, the cloud top temperature of FY-2C IR1 channel are used in this research. Based on the deviation analysis and projection correction, it is found that selected 5 ?? 5 pixels are enough for the accuracy of rainstorm forecasting. The exactly matches between the changes of time series of TBB and the evolution of convective...
