Answer 1

1. Coriolis effect: Because of the impact of Earth’s rotation on its own axis the winds move slightly to the right towards the east in the northern hemisphere and to the left, i.e. towards the west in the southern hemisphere. This effect is called the Coriolis effect.
2. Relative Humidity: The amount of water vapour in the air.
3. Leeward side: The other side of the mountain receives less rainfall. 
4. Tropical cyclones: Warmcore vortex circulation of tropical origin with a small diameter often of an approximately circular shape are called tropical cyclones. 
5. Sleet: Wet, partly melted falling snow. 
6. Chinook: The winds that move down the Rockey Mountains in the U.S.A – Canada and part of North America are known as Chinook.
7. Orographic Rainfall: The rain that occurs when the moist wind is forced to rise over mountains or other elevation in its path is called Orogenic rainfall (or) Orographic rainfall. 
8. Loo: The hot and dry winds that blow in the plains of northern India from west to east in the months of May and June are called Loos.
9.  Atmosphere: The thin layer of air that surrounds the earth is the atmosphere (or) The atmosphere is a sea of gases surrounding the Earth.
10. NASA: National Aeronautics and Space Administration – the space agency of the U.S.A
11. Particulates: The fine dust particles in the atmosphere are called particulates.
12. Homosphere: The layer of the atmosphere which consists of gases like Nitrogen, Oxygen, Argon and Carbon dioxide. 
13. Heterosphere: The layer which has heterogeneous composition and which is above 90 km of the atmosphere is called heterosphere.
14. Wind: The air that moves from areas of higher pressure to areas of lower pressure, is called wind.
15. Breeze: If the air that moves at a slow pace and we feel comfortable in it, is called a breeze.
16. Gust: The wind that comes in a short and fast burst is called a gust. 
17. Storm: The wind that comes very fast and blows things around is called a storm.
18. Planetary winds: The winds that blow constantly, continuously, regularly above the world pressure belts are known as planetary winds.
19. Mistral: The most famous cold wind that blows from the Alps over France towards the Mediterranean sea is called Mistral. 
20. Climate: The average atmospheric condition for areas over a long period of time is called the atmosphere. 
21. Dew point: The critical temperature at which saturation level of humidity is reached is called a dew point. 
22. Convectional Rainfall: The rainfall that occurs when moist air over the heated ground becomes warmer than the surrounding air and is forced to rise, expand, cool and yield some of its moisture, is called Convectional rainfall.
23. Cyclonic rainfall: The rainfall that is associated with the passage of a cyclone or depression is called Cyclonic rainfall.
