It is widely accepted that the signature of anticyclonic (cyclonic) eddies on sea surface temperature corresponds to a warm (cold) core anomaly. Nevertheless, this statement has been put question by recent regional studies showing existence inverse eddy SST anomalies: Cold Core anticyclones and, respectively, Warm cyclones. This study shows emergence these anomalies seasonal phenomenon affects ...

Blocking is associated with outbreaks of easterlies induced by a continuum features including anticyclones, cyclones or both. identification methods disagree on the levels high-latitude blocking (HLB) activity. We investigate cause disagreement in HLB activity over Northern Hemisphere obtained two 2D methods: PV– θ index and Absolute Geopotential Height (AGH) reversal method. Although both clas...

Abstract. We investigate the influence of different chemical and physical processes on water vapour distribution in lower stratosphere (LS), particular Asian North American monsoon anticyclones (AMA NAMA, respectively). Specifically, we use chemistry transport model CLaMS to analyse effects large-scale temperatures, methane oxidation, ice microphysics, small-scale atmospheric mixing experiments...
