CARTOGRAPHIC VISUALIZATION AS THE INVESTIGATION METHOD OF THE RELATIONSHIP OF NOCTILUCENT CLOUDS FIELDS GENESIS WITH TROPOSPHERIC PHENOMENA

The influence of a number of tropospheric factors on the appearance and evolution of noctilucent clouds of moderate latitudes is studied by the method of construction and analysis of synthetic maps. The fundamentals of the method allowing to compare the most accurate data of remote satellite sensing of the upper atmosphere with objective indicators of the physical state of the troposphere are considered. Both types of information have a cartographic representation, in which there are numerical characteristics of the development of meteorological phenomena. The process of building synthetic maps based on the use of standard software tools and procedures is considered in detail. A number of typical examples show the presence of a clear connection in the location of the fields of noctilucent clouds with the development of specific fast–growing processes in the troposphere. Special attention should be paid to the influence of frontogenesis and associated cyclones and occlusions on the formation of fields of mesospheric noctilucent clouds. The explanation of the revealed relations is offered on the basis of ideas of internal gravitational waves generation and their influence on the field of temperature in the mesosphere. The explanation of the revealed fact and prospects of further research of the phenomenon is offered.
