Moisture Turnover and Large-Scaled Atmospheric Processes Evolution:Numerical Simulation for Pasific Ocean Region

摘要

In practice of the super long terminal forecasts for weather and climate, there is a necessity for carrying out the special methods of observation on low-frequency oscillations of the non-equilibrium thermodynamical processes in atmosphere and hydrosphere. Hitherto standard methods of physically statistical analysis and the hydrometeorological networks data processing are used for indication of above cited phenomena. However, these methods are quite far from the standardization. We develop new methods of monitoring the low-frequency planetary scale processes on the basis of observing some summated contributions of low frequency oscillation for geophysical factors. On the basis of the low frequency processes in atmosphere there are realized the repellers of super long terminal oscillations which form basis for climatic changes and therefore geophysical predictors for the super long terminal atmospheric forecasts. We propose a new approach to calculation of the energy and angle moment balance (dis-balance). Analysis of their balance or disbalance allows to predict the large-scaled atmospheric transformations and teleconnection phenomena and to give their quantitative description. New scheme for calculation of the moisture turnover as regulator of values of the energy and angle moment balance is proposed. Special attention is turned on the singular manifestations in fields of the meteorological elements. It has developed a new scheme for calculation of the macro-turbulence regime in typical atmospheric processes which are known as the atmosphere circulation forms. It has developed physically dynamical theory for teleconnection phenomenon with application to description of the teleconnection process between the Gadley cells and southern process on the basis of El-Nin’o and arctic anti-cyclone. We carried out a group of numerical experiments on calculation of the angle moment and moisture turnover in the Pacific Ocean region and illustrated a role of circulation forms in identification of the long-periodic atmospheric processes. The experiments allow quantitatively to define a link between atmospheric turnover and atmospheric circulation forms through the front dividers position (atmospheric fronts as main moisture accumulators), between atmospheric turnover and typical low frequency process of conservation of the angle moment balance. Cited calculation allows to identify a dis-balance of rotation of the atmosphere together with Earth, which is realized under development of meridian processes of the air and vapour transfer between tropical longitudes (with large linear velocity) and slowly rotating air masses of near polar longitudes (a process of slow teleconnection). Naturally dis-balance calls for the singularity effects or sharp atmosphere reaction for attempt to delete it. During this process it is possible a transfer into other hydro-and litho-geospheres (Oorte, 1985, 1995). Such a serious action on atmosphere can be in principle by a reason for exchange of the atmospheric circulation forms that allows quickly deleting the energy and angle moment dis-balance by organization of the quick transport of the moisture and air. In conclusion it would be noted that all carried out models are naturally generalized on any region of the Earth and may be improved in essence of further increasing of the forecast possibilities
