Aside from this you can use the modeled temperature in 850 hPa (5000 ft a.s.l.) to make a rough estimate on the expected maximum temperature in 2m above the ground. However, this method does not apply to (winter) inversions. </div> </div> <div class="eI0"> <div class="eI1">ICON-D2:</div> <div class="eI2"><a href="http://www.dwd.de/" target="_blank">ICON-D2</a> The ICON dynamical core is a development initiated by the Max Planck Institute for Meteorology (MPI-M) and the Opens external link in current windowGermany Weather Service (DWD).
