November is the beginning of the cold weather season of north India. December and January are considered to be the coldest months in the northern plain. The temperature usually dips below freezing point in these two months. There are three main reasons for the excessive cold in north India during this season: States like Punjab, […]
The different climatic conditions prevalent in India are basically dependent on the seasonal changes in the temperature, rainfall, humidity etc. The climatic conditions of India can best be described in terms of an annual cycle of seasons. The climatic conditions of India can best be described in terms of an annual cycle of seasons. The
Monsoon refers to a seasonal change of winds, characterized by heavy rains. A monsoon’s season is triggered towards the end of the summer due to the difference between hot and cold air masses. The warm air mass lands on India from tropical landmasses over the Indian Ocean. Once the warm winds hit the continental land,
Scientists and meteorologists continue to study and predict the effects of EI-Nino. However, for people living in areas that are vulnerable to the yearly monsoon, this represents a major challenge, particularly in India where there is a long history of devastating floods and droughts affecting the lives and livelihoods of many. What is EI-Nino? EI-Nino
The monsoon is one of the major climatic features of India, and has a profound influence on the economy of the country. The distribution and characteristics of rainfall during the South West Monsoon (SWM) season in India is well documented by meteorological elements and in literature. There seem to be two rain-bearing systems in India.
The monsoon gathers strength as the land and ocean temperatures contrast with each other. This intensified heat transfer from land to sea develops a low-pressure region over the western part of India’s peninsula. A low pressure system is not exactly a ‘low’ temperature, but actually an area of cooling air (where air pressure is low).
The ITCZ is present only in the northern hemisphere and the southern hemisphere over the tropics which extend from the Tropic of Cancer in the north to the Tropic of Capricorn in the south. It is one of the five recognized tropical revolving storms (or low-pressure centers); it is also called a monsoon trough. These
High sun’s insolation due to apparent movement of sun between the equator and the Tropic of Cancer. Intense Solar Radiation in the Tropics makes the weather very hot and humid, while low values of solar energy in Polar Regions make the weather cold and dry. These changes in Solar Energy lead to convection and create
A large number of western cyclonic disturbances are formed over the Mediterranean Sea every winter. These disturbances are strong wind systems, strong enough to produce rainfall in the form of thunderstorms. The wind system about these disturbances is cyclonic in nature i.e. anticlockwise. Hence they are named western cyclonic disturbance by meteorologists. Many of the

During the winter season winds generally blow from north-east to south-west in the direction of trade winds. These winds are dry, devoid of moisture and are characterized by lower temperature and higher pressure conditions over the country. The term trade winds refers to the westward flowing currents of rising air that occur near tropical areas,
