In general, soil quality in most rainfed hill slopes is of such
marginal depth and fertility and is so vulnerable to runoff that
much has to be done to avoid the hazards posed by these constraints,
Glimate
By virtue of its geographical location near the equatorward
border of the Mediterranean Zone, the West Bank is characterized
by an extreme Mediterranean climate, This basically means a
comparatively short rainy season of 3-4 months and a long rain-
free summer. Seasonal variations in the length of day and night
are moderate, ranging from 14 hours for the longest day (June 21)
to ten hours for the shortest (Decenber 22), as compared to 18
and 6 hours respectively, in London,

Temperature
As a result of strong insolation, temperatures are comparatively
high but they vary considerably from one region to another,
depending on altitude, exposure to marine influence and wind
directions.
There are generally three distinctive isothermic regions in the
country: western foothills, the hilly plateau, and the Jordan
Valley. The former registers an annual average of 20°C (68°F),
the hills 17°c (63°F) and the Jordan Valley an average of 25°C (77°F).
January is normally the coldest month and August is the warmest
(see Table 11-1).

The impact on agriculture of high summer temperature, occasional
heat waves, hail storms, and frost is very grave, particularly
more so on olives and other rainfed fruit trees. This will be
analyzed later under respective sections.
Wind
The East Mediterranean coast is influenced by a number of winds,
cyclones, and anticyclones. Among the most hazardous to
agriculture, however, are the "khamaseen" and "Sharav" winds. - تاريخ
