In this region even in winter, midday desert temperatures can be very hot. After sunset, however, the clear, dry air permits rapid loss of heat, and the nights are cool to chilly.
Enormous daily ranges in temperature are recorded. The highest temperature recorded in Tiguentour is 145.4°F (60.5°C) and is probably the highest reliable temperature ever recorded
in Algeria under standard conditions. Rainfall is fairly abundant along the coastal part of the Tell Atlas, ranging from 400 to 670 mm annually, the amount of precipitation
increasing from west to east. Precipitation is heaviest in the northern part of eastern Algeria, where it reaches as much as 1000 mm in some years. Farther inland, the rainfall is
less plentiful. Prevailing winds that are easterly and north-easterly in summer change to westerly and northerly in winter and carry with them a general increase in precipitation
from September through December, a decrease in the late winter and spring months, and a near absence of rainfall during the summer months. Algeria also has ergs, or sand dunes between
mountains, which in the summer time when winds are heavy and gusty, temperatures can get up to 110 °F (43 °C).
Algeria, officially the People's Democratic Republic of Algeria, is a country located in North Africa. It is the largest country of the Mediterranean sea, the second largest on the African
continent and the eleventh-largest country in the world in terms of land area. It is bordered by Tunisia in the northeast, Libya in the east, Niger in the southeast, Mali and Mauritania in
the southwest, a few kilometers of the Western Sahara in the west, Morocco in the northwest, and the Mediterranean Sea in the north.
The fossil fuels energy sector is the backbone of Algeria's economy, accounting for roughly 60% of budget revenues, 30% of GDP, and over 95% of export earnings. The country ranks fourteenth
in petroleum reserves, containing 11.8 billion barrels (1.88×109 m3) of proven oil reserves with estimates suggesting that the actual amount is even more. The U.S. Energy Information
Administration reported that in 2005, Algeria had 160 trillion cubic feet (Tcf) of proven natural gas reserves, the eighth largest in the world.
Algeria’s financial and economic indicators improved during the mid-1990s, in part because of policy reforms supported by the International Monetary Fund (IMF) and debt rescheduling from the Paris Club. Algeria’s finances in 2000 and 2001 benefited from an increase in oil prices and the government’s tight fiscal policy, leading to a large increase in the trade surplus, record highs in foreign exchange reserves, and reduction in foreign debt. The government's continued efforts to diversify the economy by attracting foreign and domestic investment outside the energy sector have had little success in reducing high unemployment and improving living standards, however. In 2001, the government signed an Association Treaty with the European Union that will eventually lower tariffs and increase trade.
