Climatology of low-level temperature inversions at the Prague-Libuš aerological station
Temperature inversions (TIs) have been closely studied for a variety of reasons. Here, we present an analysis of low-level TIs, based on a dataset of atmospheric soundings from the aerological station at Prague-Libuš (Czech Republic). Measurements have been carried out here since 1974, at the four m...

Here, we present an analysis of low-level TIs, based on a dataset of atmospheric soundings from the aerological station at Prague-Libuš (Czech Republic).

During autumn, persistent SBTIs also often occurred, which could be linked to decreased cyclonicity.

In all seasons except spring, nocturnal SBTIs decreased almost identically at both stations. Morning SBTIs decreased as well: however, the trend was considerably stronger at Prague: and it was also mirrored by an increase in ETIs. Since only a part of these trends could be explained by changes in the large-scale circulation, other factors (low tropospheric warming, suburbanisation) are hypothesized to have affected the trends.
