Sensitivity Tests of the Initial and Boundary Conditions of the PALM Model

Popis výsledku v původním jazyce

The Parallelized Large-Eddy Simulation Model (PALM) model is an atmospheric modeling system that is capable of simulating physical processes within the urbanboundary layer and it is driven by the initial and boundary conditions taken from themesoscale atmospheric models. The motivation behind this experiment was to obtain thebest possible initial and boundary conditions for driving the mentioned model. In thecourse of this study three PALM model simulations were performed using three differentsets of initial and boundary conditions obtained from the Weather Research and Forecasting(WRF) model. The simulations were performed on an 8 km x 8 km domain in 10 mresolution which is capturing a real city area in the southeast part of Prague. A comparisonof the WRF model outputs and PALM model outputs against the observations representedby atmospheric soundings was performed as well. The conducted simulations and comparisons showed that the PALM model outputs agree well with the imposed initial andboundary conditions for the given time period confirming the need for high-quality drivingdata. Further studies with other available mesoscale models and for different weathersituations need to be performed in this regard.
