Comparison of the atmospheric response to the sea surface temperature anomalies according to observations and numerical simulation

According to the recent observations the world climatic system undergoes essential changes. Some of them are associated with the El-Nino-Southern oscillation. This paper considers the circulation and its response to the sea surface temperature anomalies with the use of the ECSib global circulation model. The model simulation and circulation anomalies...

Modeling and simulation of the urban surface impact on boundary layer structure

This study attempts to formulate an improved model for the turbulent atmospheric boundary layer (ABL). The present model employs three new ingredients: 1) an updated expression for the pressure-velocity correlation, 2) an updated expression for the pressure-temperature/concentration correlation, and 3) deduced fully explicit anisotropic expressions for the turbulent fluxes of...

Simulation of spatial distribution of the sea bottom methane hydrates and estimates of the methane fluxes into the atmosphere

The estimate of the methane emission from hydrates is based on the data indicating to the location and potential thickness of the hydrate stability zone. Gas hydrate abundance in the marine sediment depends on the gas concentration and the available pore space within certain stability limits. In this paper, we...

Methods of hydrodynamic modeling of the extreme atmospheric phenomena against theory and observational data

Extreme atmospheric phenomena include thunder-storms, heavy rains, hailstorms, and tornadoes. These events have much in common. They usually develop on the basis of a convective cloud of the vertical size exceeding 10 km. The width of strips of heavy rain, hailstorm, or tornado is approximately the same, seldom exceeding 1...
