Abstract:
MICAPS objective physical quantity data are used to analyze 82 strong convective weather causes from 2006 to 2011 in Lijiang. The main results indicate that before strong convection weather occurs, water vapor is mostly in the high or moderate humidity state, with thermal conditions mostly in a state of high temperature, high energy, and convective instability. The dynamic conditions are favorable to convective activities, such as negative vorticity at lower levels and positive vorticity at upper levels, and there was obvious cold advection, especially hails at the middle and upper levels.
