Mean of Air Temperatures in 2020 is higher than the mean average
The temperature data were analyzed by selecting stations that represent the climate system in Palestine. The analysis sample was taken for a station representing the mountainous and semi-coastal areas and the Ghor region. PMD data showed that air temperatures in 2020 were higher than the mean average by )6.5°C( in Tulkarem Station; and by (1.6°C( higher than the mean average in Jenin Station.
This significant rise in air temperatures is due to Palestine being affected by heat waves during the months of May, August and September; where the effect of which was greater on the mountainous, coastal and semi-coastal areas, hence, it made the temperature rise in these areas reaching higher percentages from their mean average. Thus, those heat waves were accompanied by a marked increase in humidity levels in the same areas.
