Klimaprojektionen, Luftverschmutzung und Belastungsgrenzen von Ökosystemen: Klimawandel, Luftverschmutzung und ökologische Belastungsgrenzen von Ökosystemen im polnisch-sächsischen Grenzraum

Im Rahmen des regionalen Klimaprojektes KLAPS werden Klimawandel, Luftverschmutzung und ökologische Belastungsgrenzen im polnisch-sächsischen Grenzraum untersucht. Mit dem vorliegenden Bericht liegt eine umfassende Analyse über die zukünftig mögliche klimatische und lufthygienische Entwicklung bis zum Jahr 2100 vor. Aufbauend auf den projizierten Klima- und Emissionsszenarien werden sowohl die Entwicklung als auch Überschreitung von Belastungsgrenzen von Ökosystemen (Critical Load) dargestellt.

Precipitable Water Content Climatology over Poland

In this work, the high-resolution spatial and temporal variability of precipitable water (PW) over Poland is presented. PW is one of the key parameters of the atmosphere taken into account in thermodynamic and radiation models. The daily PW values from years 2001–2010, calculated with the use of the WRF model, were compared with PW from soundings. The WRF modeled PW is in close agreement with measurements for the whole column of the troposphere and for individual levels: below 1.5 km, 1.5–3 km, 3–6 km and 6–10 km. The best agreement is observed in the lower part of the troposphere, especially for winter months. At the levels of 1.5 km to 10 km, the WRF model overestimates the PW values throughout the year, whereas up to 1.5 km PW is underestimated. The study shows an increasing trend of PW annual values between 1983 and 2010, but the trend is statistically insignificant. A significant positive trend with a high Sen’s slope is observed for the summer season up to 3 km in the troposphere, along with a significant negative tendency for spring. The trends in PW over Poland and Central Europe identified in this study contribute to the ongoing discussion on the observed climate changes
