Study of meteorological conditions in the near equatorial region during the period 17th to 21st June 1963 utilising United States Weather Bureau Research flight facility and other IIOE data.

V. Srinivasan and S. Raman

Except for the observations from isolated island stations and occasional ships, the near-equatorial region of the Indian Ocean is a vast data-gap area. During the period 17 to 21 June 1963, the RFF instrumented aircraft of the IIOE flew at different levels, over the near-equatorial area between Gan and Singapore. In addition to observations at flight levels, drop-sondes and cloud photography were also made. These data suggest the westward movement of a feeble trough across the equatorial region with its associated cloud and weather developments and moisture distribution. The results of the detailed analysis using the RFF data and ship's observations are presented in this paper.
