The country Congo is located in the African continent. It covers 341,500 square kilometers of land and 500 square kilometers of water. It is the 64th largest nation in the world. After gaining its sovereignty from France, Congo has become an independent state in 1960. The population of Congo is 4,125,916. Brazzaville is the capital city of Congo.

Chile is the place in the world which is known for the least amount of rainfall. The lowest average rainfall in Chile is found in the city of Arica. Average rainfall of Arica is 0.03 inch per year. Atacama Desert surrounds the city of Arica. Some parts of this desert have not received rainfall in more than 500 years. The Andes Mountains and the Chilean Coast Range surrounds the Atacama which block moisture and rain clouds from reaching the desert.

B.  Variation in the amount of rainfall in different places.`

The tropical monsoon climate experiences abundant rainfall like that of the tropical rain forest climate, but it is concentrated in the high-sun season.

A wet season from June to September, when the wind change in direction, the wind blow in the region of low pressure. Winds blow across the equator and blow over the oceans, they are warmer and carry a lot of moisture. They bring a lot of rain. Total rainfall can reach 600 mm

The Turan Type of regions experience extreme climate. It stretches from the Caspian, eastward towards the Pamirs, and from the northern edge of the Plateau of Iran northward, beyond the Sea of Aral, to the Kirghiz steppes. The climate is continental, with hot summers, cool winters and a low rainfall. Due to the availability of vast stretches of grassland, the most important occupation of people in this region is cattle and animal rearing.

The temperature recorded throughout the 24-hour period shows that there is a rhythmic rise and fall of temperature during a day. This phenomenon is called the daily cycle of temperature. The difference between the highest and lowest values of temperature recorded at a locality is referred to as the diurnal range or daily range of temperature.

Water is heated or cooled in a longer period of time than land.  Because of this peculiar characteristic of water, the coastal areas enjoy a moderate climate and the difference in temperature of the warmest and coldest months is not very large. The difference in day and night temperature is also less in the coastal area.

Temperature is a relative term implying a degree of molecular activity or heat of a substance. Temperature is recorded every day the difference between the maximum and minimum temperature for 24 hrs is called the range of temperature and the difference in mean temperature which recorded in the summer and winter is known as annual range of temperature.
