Assessment of the Climatological Hazards On some Archaeological sites in Minia Governorate
, Dr. Mohamed E. Hafez . 2015
El Mania lies in the subtropical semi-arid region at the southern edge of the temperate zone. During winter, the northern part of El Mania is affected by the sporadic passage of Mediterranean depressions which move from west to east and sometimes they persist for several days in the east Mediterranean to the north of El Mania and are associated with cold air masses aloft. Such situation can lead to a high degree of instability accompanied by thick cloud formations and heavy rain falls. Such instability conditions can extend sometimes to the southern part of El Mania, especially when the Sudan monsoon trough extends northward to the east Mediterranean. In such situation the mountainous region in eastern El Mania plays a major role in increasing the instability conditions that lead to torrential rains.
In addition to 10 mobile stations having records of Air Temperature, Surface Wind and relative humidity over Archaeological sites in El Mania, the records of tow meteorological stations in El Mania were used in preparing the above mentioned study. Most of these data covered a period of 30-50 years. This study includes charts representing climatologically normal is for sunshine duration, temperature, atmospheric pressure, humidity and precipitation, in addition to charts of the surface wind affecting El Mania.
