1 - Temperature:
Factors affecting the heat:
A - latitude: X-linked pitch circle supply and therefore temperature varies latitude when rays are perpendicular be hotter than oblique rays and when rays are perpendicular to the equator increasing tendency rays on the earth's surface as we head toward the poles.
- Terrain: rise leads to a lower temperature and frequent rainfall.
C - water bodies: a limited impact for each of the Atlantic and Indian Oceans and have no direct impact on the heat.
2 - air pressure and wind:
Nile Basin affected areas following pressure:
- Permanent area of high pressure Azzurri beyond the Tropic of Cancer, a source of the prevailing northerly winds in the lower part and the East of the Nile Basin and extends its influence southward in winter.
B - a tropical low-pressure area, which budge according to the movement of the sun which attracts virtual wind from the south and south-west at the confluence of the Atbara the Nile.
C - variable-pressure area over the crusty Asia shall be:
1 - high winter .
2 - low in summer, which helps to attract southerly winds and southwesterly fall rain on the southern Sudan and Abyssinia.
3 - rain:
Distributed annual rainfall Nile basin as follows:
- On the Mediterranean coast between 25 cm - 5 cm .
B - to the south extends the dry region of northern Egypt to northern Sudan 5 cm .
C - from northern Sudan is increasing rain as we head 5 cm - 150 cm .
D - over the Ethiopian highlands 75 cm - 150 cm .
E - on the Red Sea coast between 5 cm - 25 cm .
- Headwaters Equatorial Lakes Plateau 160 cm .
Despite the different amounts of rain, it is characterized by the following: -
1 - are all of one kind.
2 - rain summit focused on the month of August.
3 - source and one where the sun passes.
