Some applications of radio characteristics in a tropical standard atmosphere

The profiles of `M¿ in a standard atmosphere for tropics have been given for 20%, 40%, 60% and 80% relative humidity values from mean sea level to 2500 metres. They were utilized to verify the propagation conditions associated with the tropical cyclones and inversions. It has been concluded that the `M¿ profiles in the standard tropical atmosphere may be conveniently used for propagation work associated with any synoptic weather situation in India.
