The scarcity of meteorological observations has hitherto prevented spatially comprehensive and complete<br/> assessments on regional and local-scale atmospheric processes such as breeze systems on the Tibetan Plateau<br/> (TiP). Because of the high abundance of lakes, the steep topography, and the intense insolation of the TiP,<br/> lake breeze and land breeze systems might, however, contribute substantially to the local climatic and hydrological<br/> variability. The presented study aims at unveiling the influence of the lake effect over the whole TiP<br/> by using a novel high-mountain satellite cloud product, based on Meteosat Indian Ocean Data Coverage<br/> (IODC) data from 1999 to 2012, focusing on 70 lake systems larger than 72 km2<br/> . Of particular interest are the<br/> spatial and interannual variability of lake-related cloud dynamics during boreal summer and autumn. For<br/> both seasons, a significant effect of lakes on cloudiness is shown during the early morning. Its mean strength is<br/> mainly determined by each basin’s temperature difference between lake and surroundings. For boreal<br/> summer the large-scale influences of tropical and extratropical circulation pattern on the interannual variability<br/> of the lake effect are also investigated. The results show that the Arctic and North Atlantic Oscillations<br/> (AO and NAO) inhibit convective activity above lakes in the northern and central-eastern domain. A positive<br/> polarity of the Southern Oscillation index (SOI), in contrast, is in phase with enhanced convective activity.<br/> The variability of the Indian summer monsoon circulation does not affect cloud dynamics at more than two<br/> locations. Case studies are employed to illustrate interactions between cloud activity and the SOI and NAO.<br/> For this purpose satellite data are combined with the modeled 10 km 3 10 km High Asia Refined Analysis<br/> dataset on a daily basis.
