FEATURES OF POLAND CLIMATE

CLIMATE OF POLAND

Poland is in the transitional climate zone between the temperate oceanic climate in the west and temperate continental climate in the east. Masses of different clash over the area of Poland. It is the result of the position in the centre of Europe and the latitudinal geographical regions.

MAS AIR INFLOW TO POLISH

The inflow of air mass to the Polish depends on the distribution of atmospheric pressure centers over Europe. Decisive importance here are the masses of polar sea air bringing year-round rainfall. They also cause cooling in summer and warming in winter. Maps of air flows into Polish in January and July represent the proportion of the individual mass. It confirms the dominance of winds from the west.

TEMPERATURE IN POLAND

Air temperature distribution in Poland depends on three factors: the influx of air masses, altitude and distance from the Baltic Sea. Moist air from the Atlantic Ocean brings a warming in winter and cooling in summer. We can see it especially in the temperature maps in January - the farther in the east the colder. The map of annual average temperatures shows the eastern Poland is colder than the western. Continental air masses influence on it. They often "hook" of our „eastern wall”. The result of it are significant decreases of temperature in winter (even below -30 ° C). There are also the highest annual amplitude, which is typical for areas that are within the continental air.

ATMOSPHERIC PRECIPITATION IN POLAND

The average annual rainfalls in Poland oscillates between 600 mm. If we compare the first cool half of the rain maps we can see the advantage of warm summer rain. This applies the whole of Poland, including the mountains. It is typical of the whole moderate area. We can often notice cooling of warm moist air in the summer, for example, when the cold front is passing. This leads to a rapid condensation of water vapor and cloud formation. In winter is quite difficult to cool the already cold air, so that precipitation occurs less frequently – e.g. when the warm front is passing.

CLIMATIC REGIONS IN POLAND

Poland as a whole lies in a temperate climate with warm transition. This means that we are in the zone of influence of climate factors in both marine (from the west) and land (to the east). The advantage of one of them has certain effects. For example, the major impact of continental climate can cause the dry hot summer or cold winter .The rainy summer or mild winter are the result of sea climate . In spite of that in the southern part of the country there is the mountain climate. The effects of it are the reduced temperature and increased rainfalls.

POLAND - REGIONS OF CLIMATE

The map of main climatic regions shows contractual Polish division into zones of influence of the prevailing different types of climates. It is worth noticing that the zone where the influences of sea and land clash - which runs from the north to south - divided our country into two almost equal parts. This is why every year we have such a large variability of the weather every year .
