Climate conditions and temperatures

Climate conditions and temperatures

The influence of the continental and mountainous climate is felt on Mount Baba, where the Pelister National Park is located. The impact of the mountain climate is increased because it is a high mountain above 2000 m. Climate conditions on Mount Baba are influenced by several factors, such as latitude, altitude, direction of mountain ridges, vegetation, etc. The western parts of the mountain, especially those at lower altitudes, are strongly influenced by the water basins of Lake Ohrid and Lake Prespa.


Air temperature

In NP “Pelister”, there is no measuring station for monitoring the air temperatures. The analysis used data from the measuring station in Bitola. According to the HMS, the average annual temperature is 11.2 е C to 11.9 вред S. The temperature amplitude for the period 1951-1990 is 22.3 ° C (-0.4 ° C to 21.9 ° C), in the period 1991-2000 it is 23.5 ° (-1 ° C to 22, 5 ° C), and for the period 2001-2010 it is 22.7 ° C (0.6 ° C to 23.3 ° C).To determine the average temperature per zone, the isohypsy method and the correlation method were used. From the calculations the values given in Table 11 are obtained.

Soil-climate-vegetation zones Pelister National Park stretches at an altitude of 880 – 2601 m. According to the methodology of Filipovski, Rizovski and Risteski (1996), several soil-climatic-vegetation areas appear in the Park:

• cold continental CC (880-1100 m above sea level), medium 1010 meters altitude .;

• forest mountain continental FMC (1100-1300 m above sea level), medium 1200 meters altitude ;

• mountain continental  MC (1300-1650 m. C.), average 1475  meters altitude ;

• subalpine mountain SM (1650-2250 m. Asl.), middle 1950  meters altitude and

• Alpine mountain AM (2250-2601 m asl), medium 2425 meters altitude.

In the subalpine area, the average negative temperature occurs in March, and in the alpine area, in March and November.


During the analysis of precipitation in a longer period, data from several stations were taken. Based on the data from Table 12, a mathematical relationship between precipitation and altitude was made. Table 12. Average rainfall at some rain gauges by months When approximating the precipitation for different zones on Baba Mountain, the values ​​obtained mathematically can be taken as a correlation with the altitude. Thus, for the subalpine and alpine areas, the precipitation is determined on the basis of analogy with rainfall stations in similar areas in the country (Table 13).

Although there are no measurement data, the maximum expected average annual rainfall in this area should not exceed 1200 tt, at an altitude of about 1650 m. altitude.

A logarithmic dependence between elevation and precipitation with a determination coefficient of P2 = 0.996 has been determined, which means that the relationship is almost functional. Appropriate data from the stations Bitola and Kazani were used to determine the precipitation in NP Pelister for the period 1991 – 2000.

According to the data, the average precipitation in this decade at the station Bitola (590 tt> 607 tt) and at the station Kazani (805 tt> 800 tt) are very close to the average precipitation for several years (1951-1990), with that at Bitola are smaller, and in Kazani with higher values. Particularly dry years are 1993 and 2000.

1996 stands out as a wet year.

Others are close to average values.
