Explain the following terms: (a) Coriolis force (b) Jet stream

(a) Coriolis force: Coriolis force is an apparent force caused by the earth’s rotation The Coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere This is also known as ‘Ferrel’s Law’.
(b) Jet stream: There are a narrow belt of high altitude above 12.000 westerly wind in the troposphere- Their speed varies from about 110 km/h in summer to about 154 km/h in Winter Number of separate streams have been identified The most constant are the multitude and the subtropical jet stream.
