Why is the Sahara so hot?

Answer 1

The Sahara Desert can get up to 58 ºC (136.4 ºF), which was the record set in Libya in 1922. Summer daytime temperatures over 50ºC are not uncommon. However, the reading was thrown out as it was concluded the most compelling scenario for the 1922 event was that a new and inexperienced observer, not trained in the use of an unsuitable replacement instrument that could be easily misread, improperly recorded the observation and was consequently in error by about seven degrees Celsius. A temperature of 134 degrees F. measured in Death Valley in 1913 holds the official record.

Answer 2

The Sahara desert can be extremely hot in summer particulary in the heart of the desert and remains hot in winter particulary in the south part of the desert. The Sahara desert heat and aridity is caused by the atmospheric circulation of air masses over the world. The story begins in the equator where the Sun radiation is the most intense. The Sun heats up very strongly the ground and the atmosphere in the equators which cause the air to lift up, to rise and to form high powerful clouds such as the Cumulonimbus clouds and these clouds produce heavy rains over the equator region. The air has now lost a large part of his humidity over the equator and is now very dry. Then the dry air begins to go in lower latitudes, towards the poles and the air cools off. Once, the dry cool air reached the subtropical regions, it starts to descend, to sink which warms up the air and dries out adiabatically and it's here the hot deserts regions form. This part of the atmospheric circulation is called the Hadley Cell and this cell form the subtropical ridge, a large subtropical zone with a dry sinking air that prevent cloud and rain formation and with a lot of the sunshine. The subtropical ridge leads to the formation of hot deserts in the Northern Hemisphere such as the Sahara, the Libyan Desert, the Arabian Deserts, the Mojave and the Sonoran Desert and many other but also in the Southern Hemisphere with some well-known hot deserts like the Atacama Desert, the Australian Desert, the Namibian Desert.

Answer 3

The question is a generalization, Africa has many climatic and geographical zones: tropical jungle, Savannah grasslands, desert, temperate Mediterranean areas, winter and summer rainfall areas even areas where it snow in winter etc.

The main reason why large portions of the continent are hot (tropical or desert) is because large sections fall across the equator, as well as two very large sections that fall within the tropics of Capricorn and Cancer. This means (in general) the continent has a very high exposure to sunlight, more so than countries in the northern hemisphere (e.g. Europe).

Answer 4

The hottest air temperature ever reliably recorded in a desert was 134 degrees F in Death Valley of the Mojave Desert in California on July 10, 1913. An even warmer temperature of 136 degrees was recorded a few years later in Libya but that has been discounted as inaccurate as it was not properly measured by untrained Italian soldiers. A recent ground temperature was measured by a satellite in Iran that was even hotter but the ground temperature does not reflect the temperature of the air above it. Anyone who has walked barefoot over an asphalt parking lot in summer can attest to that.

Answer 5

Wal-Mart and BestBuy are two retailers among others that offer prepaid cell phones for sale. You can purchase these phones brand new without a contract. To get minutes, you would need to purchase refillable minutes cards that work similar to a prepaid debit card. You can purchase an unlimited number of these cards and refill your prepaid account as needed. Many mass merchandise retailers such as Wal-Mart sell these prepaid minutes cards in the checkout lanes.

Answer 6

Lack of water in an area,makes it dry.

So...the sun beats down on the dry land and makes it so hot.

Answer 7

it is because the sun hits itself very high in Africa so the hot sun gives hot weather. that is why Africa is very hot.

Answer 8

The Sahara desert is one of the hottest desert in the world. The Sahara desert is also the worlds largest sub tropical desert.
