Air Temperatures in 2021 are higher than the mean average
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 Al-Aghwar region. PMD data showed that air temperatures in 2021 were higher than the mean average by (3.4°C (in Tulkarm and Jericho stations.
This significant rise in air temperatures is due to Palestine being affected by heat waves during the months of July, August and October, 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.
