Answer:
1. element of climate is temperature, atmospheric pressure, humidity, precipitation and topography.
4. season means one of the period of different
Answer:
1. weather refers to short-term changes in the atmosphere, climate describes what the weather is like over a long period of time in a specific area. Different regions can have different climates. ... Weather tells you what to wear each day. Climate tells you what types of clothes to have in your closet.
2.The most significant of these elements are temperature, atmospheric pressure, wind, solar irradiance, humidity, precipitation, and topography.
3. A minimum 30 year data series is needed. A double 30-year period or longer period would be better to be used. The trend analysis applying a data series shorter than 30 years is less relevant because normal climate is usually defined for three decades.
4. the Hindu calendar of tropical and subtropical India, there are six seasons or Ritu that are calendar-based in the sense of having fixed dates: Vasanta (spring), Greeshma (summer), Varsha (monsoon), Sharad (autumn), Hemanta (early winter), and Shishira (prevernal or late winter).
5. India hosts two climatic subtypes- tropical monsoon climate, tropical wet and dry climate that fall under this group. 1) The most humid is the tropical wet climate—also known as tropical monsoon climate—that covers a strip of southwestern lowlands abutting the Malabar Coast, the Western Ghats, and southern Assam.
6. The factors affecting the climate of a place are referred to as controls and are latitude, altitude, pressure and wind system, distance from the sea, ocean currents, and relief features. Altitude is another factor controlling the climate of a place.
7. As you go to higher altitudes, there are less air molecules pushing down on you (lower pressure). ... Therefore, the air temperature is lower at higher altitudes.
8. The Himalayas prevent the cold winds from Central Asia from entering the subcontinent. It is because of these mountains that this subcontinent experiences comparatively milder winters as compared to central Asia. ... India lies in the region of north easterly winds.
9. The easterly jet streams cause tropical depressions during the monsoon as well as October-November months. Jet streams are fast flowing winds blowing in a narrow zone in the upper atmosphere. In winter, the subtropical westernly jet streams bring rain to the western part of India.
