Many activities such as travelling and school calendars depend upon the seasons and climate of an area. The meteorological department of India bifurcates the months of a year according to the seasons as follows:. These classifications are made keeping in mind the changes in temperature, air pressure, topography, amount of rainfall, changes in directions and intensity of air current etc. They are divided among the twelve months of a calendar with each season having a span of exactly two months.

Each season has its own beauty and is loved for different reasons. Typically, the seasons in India are divided into 4 categories which are summer March — May , winter December — February , monsoon June — September and post monsoon also known as north east monsoon October — November.

The span of these seasons varies from 2. During the winter season the temperature varies from 10 to 15 degree Celsius. Northern part experiences snowfall along with rain. December and January are usually the coldest months. In winter time, it is observed that nights are longer than days. India being a tropical country, summer is a bit extreme in certain parts. The temperature is highest in April and May and varies from 32 to 40 degree Celsius. In summer the days appear comparatively longer than nights.
The Indian Monsoons typically start in June and extend till September. In India, majority of precipitation is caused by the south — west monsoons. The south west monsoon originates from the Bay of Bengal and Arabian Sea. The months of October and November fall under the post monsoon season. Some parts of India receive their precipitation from the north east monsoon such as Tamil Nadu.
Winter Season Essay
This season marks the transition between a wet and dry season. The temperature slowly starts lowering during this transition. So, these are the seasons of India as classified by the meteorological department. The span and intensity of these seasons are not fixed and are subject to change depending upon certain external environmental factors such as air pressure, direction of air currents, cloud formation, anthropological factors such as deforestation and pollution etc.
As the environmental factors experience major changes, these changes are reflected largely in the duration and intensity of the seasons in India and also the neighboring parts. Hence, due to vast geographic scale and varied topography generalizations cannot be made for the seasons of India. Anthropological factors such as pollution have caused havoc to the generally smooth seasonal cycles of India.

Various activities such as deforestation, urbanization, industrialization, etc have brought an adverse effect on the seasonal changes in India. Excessive deforestation for the construction of residential buildings and industries to cope with the growing demands of the people has led to loss of valuable green cover in the country which in turn has caused disturbance in the rainfall pattern and has also led to the loss of valuable soil cover and floods in various parts of the countries.
Due to the change in rainfall and temperature patterns people have to face extreme climatic conditions. Indian monsoons lead to floods in parts of north east and northwest while the southern parts experience drought to the extreme levels. These changes are confusing scientists and meteorological experts from a considerably long time. It is difficult to assign exact reasons to these adversities. These changes can be permanent or the climate might return to its normal state. Due to the increase in C0 2 concentrations in the atmosphere along with the stimulation of production of greenhouse gases, winters are becoming relatively warmer in tropical countries.
The presence of these gases in the atmosphere along with the presence of favorable conditions for their oxidation has led to thinning of the ozone layer. Ozone layer obstructs the harmful U. According to past records, it is true that climate change is a natural phenomenon but the research from the past few decades suggests that the sudden exponential changes are a result of increasing population and industrialization.
Many scientists argue about the irreversibility of these climatic conditions and changes but many others are optimistic about the new researches and enlightenment among people about the changing scenario. Numerus books, research papers, documentaries, movies etc have been introduced on the growing concern of global warming and its association with climate change. In India, different regions experience different climatic conditions.
While in summers, certain regions in the country may experience extreme heat others may have a rather less hot but humid climate. The tropical and sub-tropical parts in India consist of four seasons namely winter, summer, monsoon and post monsoon.
As the change in day and night is caused by the rotation of the earth on its axis similarly the change in seasons is caused by the revolution of earth around the sun in elliptical orbits. The difference in the intensity of seasons in different parts is a result of the slight tilt of the earth. At different times during the year, the northern or the southern axis is closer to the sun.
During this time the part closer to the sun experiences summer as it recieves direct heat from the sun. Whereas in winter, the earth moves away from the sun in the elliptical orbit and hence the sun rays have to travel a longer distance to reach the earth, which results in lower temperature on the earth at that time of the year. The above stated are the natural processes which bring about the change in the seasons around the year. The changes by these processes are subtle and people can easily adapt to the whereas the change in seasons caused by anthropological factors such as emission of greenhouse gases are more adverse and extreme and cause difficulties to living creatures and even property.
This diversity in topography affects the climatic and cultural conditions in various parts of the country. India can be regarded as both tropical and sub tropical as the tropic of cancer passes roughly through its center. The Northern Part is kept relatively warm as the Himalayas act as a barrier to the cold central Asian wind entering the country.
Extreme temperatures recorded in India are 51 degree Celsius in Rajasthan and the lowest being degree Celsius in Kashmir. The north pole begins to move away from the Sun. The Sun rises lower in the sky so the days start getting shorter. When the Sun is at its mid-point in the sky, we reach the ' autumn equinox ', around 22 September.
Day and night are both 12 hours long and its the beginning of autumn. The Earth continues on its path, and our north pole starts moving towards the Sun again. The Sun moves upwards in our skies and the days continue getting longer. Again, we reach a midpoint when day and night are both 12 hours long. This is called the ' vernal or spring equinox ' and happens around 21 March. The Earth's movement around the sun causes the seasons, but it does not affect the temperatures during the seasons.
Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun at the beginning of January! During the summer, the sun's rays hit the Earth at a steep angle because the sun is higher in the sky. The light does not spread out very much, thus increasing the amount of energy hitting any given spot. The long daylight hours during the summer months allow the Earth plenty of time to reach warm temperatures. This is why the days are hotter in the summer months.
Because the sun is higher in the sky our shadows are shorter than they are in the the other three seasons. During the winter, the sun's rays hit the Earth at a shallow angle because the sun is lower in the sky. These rays are more spread out, which minimizes the amount of energy that hits any given spot.
The long nights and short days prevent the Earth from warming up. This is why we have cold winters. Summer is warmer and winter is colder because of the length of our days and nights. In the summer daylight lasts longer and night time is shorter. Winter Months In winter the days are shorter and the nights longer. There is more time for the sun to warm us during long summer days. And short winter days have long, cold nights.
