Answer» 1.Jet streams are air currents found in the tropopause which is the transition between troposphere and stratosphere. These are westerly flows which blow south of the Himalayas, all through the year except in summer. The western cyclonic disturbances experienced in the north and north-western parts of the country are brought in by this westerly flow. In summer, the subtropical westerly jet stream moves north of the Himalayas with the apparent movement of the sun. An easterly jet stream, called the tropical easterly jet stream blows over peninsular India, approximately over 14°N during the summer months. 2.Themonsoon"bursts" refers to the normal rainfall that increases suddenly and continues constantly for several days. A phenomenon related with the monsoonis its tendency to have 'breaks' in rainfall. It refers to wet and dry spells. In. other words, themonsoonrains take place only for a few days at a time. |
