Why is the temperature and pressure high in winter in southern Europe?

Mainly due to the temperate continental climate.

The region includes temperate continental humid climate and temperate continental semi-arid and arid climate. Generally speaking, Eastern Europe and Central Europe belong to the former, while Southern Europe and Eastern Europe belong to the latter.

The climate in eastern Central Europe has the nature of transition from maritime to continental. The influence of polar ocean air mass is dominant here all year round, with mild winter and low temperature in summer. The average temperature in 65438+ 10 is generally 0-4℃, which can reach -5℃ in a few areas, and the average temperature in July is generally around 18℃, which can exceed 20℃ in a few areas. However, ice air masses and polar continental air masses often invade, so the weather is very unstable. Precipitation is greatly influenced by topography, which is generally 500-600 mm in plain areas and more in summer.

The climate in eastern Europe is divided into two regions: the north and the south. The mixed forest belt in the middle is in the north, which belongs to the humid continental climate. It is greatly influenced by the polar ocean air mass. There is no severe cold in winter and the temperature will not be too high in summer. The average temperature in 65438+ 10 is between -5℃ and 14℃ in most areas, and the average temperature in July is less than 20℃. The annual precipitation is generally 500-600 mm, which is more in some areas. The southern region is located in the Eurasian high-pressure axis (called "Voyekov high-pressure axis" by the Soviets) and the area south of the high-pressure axis, and the related westerly airflow and cyclone activities are obviously weakened, and the anticyclonic weather is increasing. The annual precipitation is generally 300-500mm, the southeast is below 200mm, and the summer temperature is between 20-25℃. The water balance of the whole southern district is negative, belonging to temperate continental semi-arid and arid climate. In the natural landscape, most areas are grasslands, and the southeast is semi-desert or desert. Southern district is rich in heat resources and fertile land, and it is the main agricultural area. However, due to insufficient precipitation and great changes, droughts often occur.
