Based on the FY2D/E satellite and thunderstorm data in summer from 2010 to 2014, the satellite image characteristics of newborn thunderstorms and their formation mechanisms in the Eastern QinghaiXizang Plateau are analyzed. The results show that the satellite image characteristics of thunderstorms have obvious features, and the cloud top, which has a high correlation with altitude, is below the tropopause. In general, the TBB of the IR channel (IR1) often ranges from -55 ℃ to -10 ℃, and the TBB of the vapor channel (IR3) has a high frequency from -50 ℃ to -30 ℃. The TBB difference between IR2 (TBB of the splitwindow channel) and IR1 has a high frequency around -33 ℃, and the TBB difference between IR3 and IR1, which is greater than 0 ℃, reaches 83%. In addition, the differences between the surface and air temperature often appear from 5 ℃ to 15 ℃, while the surface temperature is basically from 25 ℃ to 30 ℃ and the relative humidity between 40% to 55% and 30% to 50% in regions Ⅰand Ⅱ. But the differences between the surface and air temperature often range from 5 ℃ to 10 ℃, and the surface temperature is concentrated mainly from 30 ℃ to 35 ℃ in the Ⅲ region. The differences between the surface and air temperature, surface temperature, and relative humidity conditions are reasonable and can be good indicators of newborn thunderstorms in the eastern QinghaiXizang Plateau.
