For each increasing of the absolute altitude by 100 m the mean annual temperature goes down by 0.6 degrees C, the average of maximum values by 0.35 degrees C, the minimum values by 0.43 degrees C, the number of clear day by 2.4 degrees C and the real evoapotranspiration by 3.2 mm. At the same time, the rainfalls amount is increased by 3.2 mm, the number of cloudy days by 3.6 and the annual relative humidity of air by 1%; the annual rainfalls amount is related to altitude with with few exceptions printing out their local character higher altitude. The temperature differences between some relief types could be noticed epecially during the clear and mild nights by 3-4 degrees C. The daily amplitude is higher (22.4 degrees C) at the bottom and lower (15.1 degrees C) at the top. Therefore, on the higher types of relief over 40-65 m altitude wich are more protected against frosts should be planted species more sensitive to warmth and on the lower ones species with more resistance and late blooming season
