| Abstract: | The optimum microwave link design
requires the knowledge of rain rate distribution as well as of the duration
statistics of the rain events. The rain rates measurements at Ahmedabad, a
tropical location in India, are analysed and models for various event
parameters are developed using three years of continuous measurements. The
average number of cases with at least 1 min event duration shows an exponential
dependence on the rainfall rate with a correlation coefficient of 0.93. Also,
the average durations for different rainfall rates are found to follow a power
law with a correlation coefficient of 0.97. It is found that the average
duration more effectively represent the event duration at higher rain rates.
The results are compared with those obtained for the temperate and other
tropical locations to indicate the distinctiveness of the studied parameters
over the location. It has been observed that although the tropical locations
show similar qualitative features, the characteristics of the Indian region
show quantitative difference from other tropical regions. |
