Abstract

The results of special radiosonde soundings extending upto 1000 ft made on certain selected dates and at certain selected hours during the winter season 1957-58 and pre-monsoon season 1958 over Dum Dum airport are discussed. The results indicated the formation of ducts at certain hours. The variations of the meteorological data with the progress of night are shown in a tabular form.

The radarscope observations at the corresponding hours are also discussed. On some occasions the duet heights were as high as 600 ft and prevailed for the whole night. These duets extended horizontally in all directions to about 50 miles. The attenuation produced by appearance of fog/mist over the station and its masking effect on the ground clutters are also discussed. The mass concentration of water droplets on different dates has been calculated and shown in a tabular form.
