Input and output files for WRF urban simulations for the metropolitan area of Tel-Aviv

We implement and verify for the first time four Weather Research and
Forecasting model urban configurations, focused on the coastal
metropolitan area of Tel-Aviv (MTA) using updated land use and
morphological maps. We analyze the mesoscale summertime flow and the urban
canopy (UC) role in the occurrence of different hodograph dynamics
observed within MTA at night. These events may be significant in air
quality research. The four configurations – bulk (MM), single-layer
(SLUCM), multi-layer (BEP), and BEP coupled with the building energy model
– reproduce the observed diurnal temperature and wind cycles, with similar
10m wind direction bias and RMSE (15o and ~30o, respectively),
with preference for MM and SLUCM at night. However, the SLUCM shows the
lowest skill for the 10m wind speed (WS) (bias and RMSE 1ms-1), and the
BEP shows the largest underestimation of the 2m temperature, ~-2.5oC. In
the SLUCM, the WS increases over an UC and with increasing building
heights. These results call for a re-examination of the SLUCM WS
parameterization. The simulations show that at night, a convergence line
(CL) builds up with the urban heat island, downstream of the NW flow. West
of the CL, the wind continues flowing from the sea, and rotates
anti-clockwise to form a non-elliptical sea-breeze hodograph. Removing MTA
UC restores an elliptical hodograph. East of the CL, the UC supports an
elliptical hodograph with a clockwise rotation through the NE sector,
previously reported as dynamically unstable. We expect such wind hodograph
dynamics within similar coastal metropolitan areas.
