113: Westerlies in southern hemisphere are stronger and persistent than in northern hemisphere. Why?
1. Southern hemisphere has less landmass as compared to northern hemisphere
2. Coriolis force is higher in southern hemisphere, as compared to northern hemisphere
Which of the statements given above isl are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation:
The Southern Hemisphere is the southern portion or half of the Earth. In comparison to the Northern Hemisphere, the Southern Hemisphere has fewer land masses and more water. The South Pecific, South Atlantic, Indian Oceans and various seas such as the Tasman Sea between Australia and New Zealand and the Weddell Sea near Antractica made up around 80.9% of the Southern Hemisphere. Land comprises only 19.1%. In the Northern Hemisphere, the majority of area is composed of land masses instead of water.
- The Coriolis force (1) causes objects to deviate to the right of their direction of motion in the Northern Hemisphere (and to the left in the Southern Hemisphere (and to the left in the Southern Hemisphere): (2) affects the direction an object will move across the earth's surface, but has no effect on its speed: (3) is strongest for fast-moving objects and zero for stationary objects : and (4) is zero at the equator and maximum at the poles.
Coriolis force is equal in both the hemispheres at their respective latitudes.
