...season 2007/2008..... AMOMFW 2008/Ralf Brauner(AWI/DWD)
extended season from 25th of Oct 2007 - 16th March 2008 due to the new construction of NEUMAYER III • done by Hajo (1) and Ralf (2) in three periods • more than 3500 forecasts were distributed (1200 in 2003/03!) • 5 medevac flights, unfortunately one helicopter crash at Neumayer Station AMOMFW 2008/Ralf Brauner(AWI/DWD)
no boomerang flights from Cape Town to Antarctica in the past seasons! AMOMFW 2008/Ralf Brauner(AWI/DWD)
flights done by Basler BT67 „Polar5“ AMOMFW 2008/Ralf Brauner(AWI/DWD)
Experience with AMPS and ECMWF • during the season both models work very accurate • AMPS has still an advantage in forecasts for surface winds • EPS meteograms of ECMWF are used as the main technique for forecast up to 4 or 7 days • the web access is a great advantage for AMPS • humidity in AMPS (low stratus) is sometimes higher as observed AMOMFW 2008/Ralf Brauner(AWI/DWD)
humidity in AMPS (low stratus) 12th Feb. 2008: Clear sky over Halley, but low stratus over the sea AMOMFW 2008/Ralf Brauner(AWI/DWD)
A lot of humidity in the lower layers in the AMPS meteogram AMOMFW 2008/Ralf Brauner(AWI/DWD)
No clouds in the ECMWF meteogram AMOMFW 2008/Ralf Brauner(AWI/DWD)
