As is known, the Great Red Spot (GRS) one of most mysterious sights in solar system and a strong storm that quite large. According to laws hydrodynamics gas dynamics, it should have disappeared several centuries ago, but scientists still observe cannot accurately explain this phenomenon. Since turbulence atmospheric waves GRS region absorb energy its winds, vortex loses by radiating heat. In wo...

Oxidized mercury (Hg(II)) is chemically produced in the atmosphere by oxidation of elemental mercury and is directly emitted by anthropogenic activities. We use the GEOS-Chem global chemical transport model with gaseous oxidation driven by Br atoms to quantify how surface deposition of Hg(II) is influenced by Hg(II) production at different atmospheric heights. We tag Hg(II) chemically produced ...

The Eastern Kamchatka Current (EKC) is the western boundary current of North Pacific subpolar gyre. Southeast Peninsula lies a large anticyclonic eddy, Eddy (KE). This eddy quasi-stationary. More generally, oceanic region east EKC contains many eddies, several them and long lasting. Using surface currents derived from altimetry, particle tracking simple two-dimensional numerical model fluid flo...

Many previous studies of the occurrence blocking anticyclones, their characteristics, and dynamics have defined onset longitude using one-dimensional zonal index type criterion proposed by Lejenas Okland. In addition to examining event itself, was determined start at nearest five degrees National Centers for Environmental Prediction/National Center Atmospheric Research Reanalyses that were used...

The causes of wintertime precipitation decrease in the Southern Coast of Caspian Sea (SCCS) compared to its counterpart in autumn, is investigated with the use of synoptic stations daily dataset of SCCS and gridded NCEP/NCAR and NOAA dataset. The structure of atmospheric circulation and synoptic and physical conditions over the Caspian Sea region which are dominate in the winter and autumn prec...

Mineral dust affects health, climate, and ecosystems in various ways. East Asia is one of the major sources mineral world. This study examines year-to-year variability deposition over Japan April from perspective large-scale atmospheric circulations using aerosol reanalysis datasets for period 2011 to 2017. The increased explained by intensified transport Mongolian Plateau anomalous westerly wi...
