Analysis of the Formation of Vortex Tube and Thermals Above Urban Area by Urban Meteorological Model Based on Large Eddy Simulation

Convective genesis is subject of our research. Some researchs suggest that urban heat and shape affect the convective genesis. The aim of this reasearh is understanding which factor is the most strong on the generating process. 2 patterns of simulation by using urban meteorological model based on large eddy simulation is conducted. As a result of this sensitivity test, the effect of urban heat is greater than the effect of urban shape. In addittion, Multi-sensor observations are being performed in Kobe City. And in this research by comparing the result of simulation with observation (wind profiler, doppler lidar, and radio sonde) validity of simulation result is verified.
