As we go higher in the atmosphere, atmospheric pressure drops and the air goes on getting thinner. That's why mountain climbers sometimes need bottled oxygen to breathe. It becomes difficult to breath as the air is thinner.

A transitional type of climate found between the equatorial forests & trade wind hot deserts is known as Savanna type of climate. This climate is confined within Tropic of Cancer & Tropic of Capricorn. The Savanna type of climate is characterized by humid summers and dry winters. Africa, Australia, South America and India have Savanna type of climate. Temperature range of this climate is 18° – 30° C. This is also known as Sudan type of climate.

Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less as compared to land. That is why it doesn't get too hot or cold. 

The Great Nicobar island is the Indian island that lies closest to the equator. The Indira Point is the southernmost point, i.e. The point closest to equator.

The average condition of rain, temperature, and moisture for over more than 35 years in known as climate. In other words, climate can be simply defined as the average weather of a particular place. The term climate denotes a description of aggregate weather conditions.

Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum.

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum.  The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency.

Radiation from the Sun. Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum.

Our sun is the main source of energy and heat. It provides solar energy or fuel for the process of weather and climate. The energy emitted by the sun is known as solar radiation. The incoming solar radiation to the earth is known as insolation.
