[AAS04-11] Satellite and model analysis of short-term precipitation characteristics over tropical oceans
Keywords:Convective activity, Short-term variability
To provide observational knowledge of short-term temporal variability of tropical convection and model diagnosis, the current study was conducted to explore short-term characteristics related with convective activity using satellite observation referring to Masunaga (2012) and compare model results of different spatial resolution simulated by the Nonhydrostatic Icosahedral Atmospheric Model (NICAM).
The current study focuses on temporal variability of precipitation, brightness temperature at 11 um related with cloud top temperature, and column water vapor. These parameters are obtained by both TRMM and Aqua satellites. Parameters are sorted as relative time from a basepoint of Aqua observation, which enables to estimate autocorrelation on an hourly time scale. These results will be compared with NICAM’s results at fine and coarse horizontal resolutions.
