Title: Need for development of tethered balloon facility for basic studies of Indian summer monsoon

Abstract: Major part of the easily precipitable moisture in the S-W monsoon air mass originates from evaporation over the Arabian Sea and its subsequent up[ward transport by vertical mixing. It is commonly thought that vertical mixing in the air mass, particularly over the East Arabian Sea, is vitally important for rainfall activity over the west coast. A programme for assessing this vertical mixing should therefore be very valuable for understanding the dynamics of the monsoon from measurement of vertical profiles of radon in the air mass. The most practical method for measuring radon in high altitude air, at present, requires bringing about 20 litres sample of this air to the laboratory. This can be best done using tethered balloons which can carry the samplers to the desired altitudes and then bring them back filled with the desired samples of air. In addition to procuring samples of high altitude air for radon measurements, same balloons may be used for obtaining better and more detailed conventional meteorological data than hitherto available.
