List of Figures
Fig. 1.1
WRF nested domain with 7 km horizontal resolution,
showing USGS 2006 classified land use, projected
on a LAT/LON grid with the coordinate
system WGS 84 Zone 32 N. The urban areas
of interest are marked ........................................................

Fig. 1.2
Probability density functions (PDFs) extracted for
the central 7 × 7 km pixel of a selected urban area.
The blue line indicates the probability density curve
for extracted monthly mean temperatures in the past
(1971–2000), the red line shows the same for the future
(2021–2050) period. The vertical lines illustrate
the 95th percentile for each plot and time frame ............... 10
Fig. 1.3
Number of days with PET assessment classes
in the climate normal period 1961–1990 compared
to the frequency in 2021–2050 and 2071–2100
at 6:00 a.m. Data basis: REMO A1B and B1 scenario ...... 13
Fig. 1.4
Flow chart about the use of SURFEX with topography
[m] and the gridpoints that include urban surface
(right panels; red); white dots indicate
the observational stations in the right panels ..................... 16
Fig. 1.5
Spring 2-m mean temperature (°C) of
ALADIN-Climate (at 10 and 1 km resolution
– left and middle panel) and SURFEX
(at 1 km resolution – right panel) over
Budapest for 1961–1970 (Vértesi 2011) ............................ 17
Fig. 1.6
Difference of monthly mean temperature (°C)
between SURFEX and observation in
Kitaibel street (filled squares) and
Pestszentlőrinc (open squares)
