The Description of Important Historical Moments in Terms of Meteorological Aspects

The purpose of this paper is to present the role of meteorology in certain important historical moments both from the last century and from the present one.

To investigate these cases from a meteorological point of view, we used reanalysis data, from some climatological databases, for the events of the last Century and for the events of the 21^st Century, we relied on various information that allowed us investigation of the atmosphere, at all levels (synoptic maps at different levels, satellite imaging, backward trajectories, radioactivity data, etc.). Although during the First World War, the investigation of meteorological parameters was limited only to the ground level, in critical moments, the weather forecast decided the fate of some missions carried out on the front during that period. Over time, technology has advanced and the investigation of the atmosphere is carried out on a multitude of levels, using modern investigation technology, with active or passive sensors, located on the ground or on equipment from space.

Forecasts have greater accuracy, and information is easily transmitted to the population and institutions of national interest too. In case of natural or anthropogenic disasters, accurate weather forecasts allow quick decisions to be made for the safety of the population.

More recently, there are stations (national and international) that also monitor aerosol stratification.

The meteorological stations have been modernized and automated, the synoptic maps from the ground and from the altitude are at “one click” away from us. Meteorology has become a field of interest for industry, transport, military and, last but not least, for the safety and security of the general population. In this paper we will show the progress in this field of activity and the implications in people’s everyday life.
