Mp Board Class 10th Social Science Solution Question 6.
Describe the atmosphere conditions on the basis of following isobar?
Answer:
- Is cyclone and
- Is anti – cyclone.
In cyclone when the isobars form concentric closed circles, the smallest circle in the center indicates a low pressure center. Air moves from a high pressure area to a low pressure area. In the Northern Hemisphere, the wind blows in a counter clock – wise direction in a cyclone. In the Southern Hemisphere, the wind blows in a clock – wise direction. These cyclones move in the direction of pressure center.
Air pressure in little in the center of shallow depression but it is very little in deep depression. Deep depression is surrounded by more than one isobar and shallow depression area is surrounded by single isobar and partially surrounded by other isobars. Isobars are depicted in a dispersed way in shallow depression and the isobars are shown close in depression. Under this condition the air mass rises above and takes the form of clouds and rains. Thus the weather conditions are rough in the cyclonic area.
The Anti – cyclone is opposite of cyclone. Anti – cyclone have high pressure in the center and they are surrounded by low pressure. The center of high pressure is called ‘Highs’. This is the point of intersection of two wedge lines. The isobar is usually circular, the winds blow in clock – wise direction in the Northern Hemisphere and counter clock – wise in the Southern Hemisphere.
The winds blow outwards from the center in such condition. Anti – cyclone are weak and stay at one place for quite some times. The wind is slow and keep varying. Anti – cyclone do not move in a definite direction and the center is calm. In the front the winds blow in a definite direction; the sun is bright and sky is clear and dry. Sometimes there are drizzling rains.

Answer:
Wedge is a triangular high pressure area. The isobars are V – shaped with rounded peak. The peak indicates towards the low pressure area. In the center of the edge, the air pressure is the highest and it goes on diminishing towards the peak and edge. The line joining the highest pressure point and the peak point it called crest line.

What do you mean by international climatic indicators?
Answer:
The facts and information received from observatories are indicated in the map with the help of figures, signs and symbols which are accepted internationally.

Indicators of air speed:
The system of measuring the wind speed was pioneered by the British naval chief Vufort in 1805, that system is being used even today with some modifications. In the Indian Weather maps. Wind indicator which are being used are different from the one developed by Vufort.
This wind indicator shows the speed through its rear wings and the front end indicates the direction. Through these wings any speed can be indicated. Normally by changing half of the wind a difference of five knots occurs.

Question 4.
Explain the variation of air pressure with the help of Indian map and draw the conclusion related to the trends?
Answer:
Variation in air pressure:
In the weather map the air pressure is shown with the help of millibar. This is normally indicated by the difference between two millibars. The higher number shows high air pressure and the lower number shows low air pressure.
Sometimes low pressure is indicated by writing L and high pressure by H. This is read like contour lines. The air always blows towards low pressure area from the high pressure area.
1. Normal distribution of air pressure:
High and low pressure zone.
2. Speed of cyclones:
With the help of the air pressure map, we can explain the conditions of air pressure in the atmosphere. From the map given we see that the air pressure was 2 millibar less than the normal. Only in two zones the pressure was normal. The mountain region of North, Bihar, Andaman and Nicobar and Eastern Myanmar the air pressure was normal.
