Abstract. Considerations regarding the variability of Earth-Sun geometry and the climate variability in south-western Romania. The variability of the Sun-Earth geometry is particularly high during the year due to the specific trajectory of the planet Earth around the Sun, the rotation motion of the Earth around its axis, the inclination of the rotation axis with respect to the plane of the ecliptic and the axis of precession. As a result, the variability of the duration of days (and nights) occurs on Earth and the amount of energy received by the Sun varies continuously. Corresponding to these variations in correlation with the characteristics of the Earth's surface and the general circulation of the atmosphere on the Earth, large climatic variations occur which determine at the temperate and polar latitudes the succession of the antipedes. All these variations are reflected in the great climatic variability of one year. In this paper we analyze in detail the variability of the Earth-Sun geometry and its correlation with the climatic variability in southwest Romania (Oltenia). The conclusions are useful for weather forecasting and seasonal climate forecasting as well as those interested in climate variability.
Key-words: Earth-Sun geometry variability, climate variability, Earth's thermal equator, polar climate front.
