THE total seasonal rainfall during the year's southwest monsoon (June 1 to September 30) for the country as a whole was 99 per cent of its long-period average (LPA), which, being within plus or minus 10 per cent of the LPA, can be termed as a `normal' monsoon.

The skewed pattern of rainfall experienced across the country during this year's monsoon appears to be an anomaly.

Two cases of intense western disturbances which affected the northwest India have been investigated using the India Meteorological Department’s operational limited area analysis and forecast system. The model results are compared with the synoptic observations, which have been enriched by additional stations installed under the national project ‘Parwat’. The analysis shows that the 24-hour model forecasts are in good agreement with the observations both in respect of western disturbance’s movement and intensification.

Rainfall and maximum and minimum temperature data of 32 years (1970-2001) at Semiliguda, Koraput (Orissa) were analysed to study the weekly, monthly and yearly drought investigation by studying the water balance. The IMD method was adjusted more suitable for drought identification than the revised IMD method.

Statistics relating to the date of onset of the southwest monsoon over Kerala for the 100-year period 1891-1990 reveal that the mean and median dates of onset for south Kerala are 31 May and 1 June, with a standard deviation of 8.5 days. Declaring the date of monsoon onset is not a straightforward matter. However, rainfall pattern, uppper air circulation features and INSAT cloud pictures are useful guides, and these indicate that the onset date in 1990 esd 17-18 May. During 1891-1990 there have been onlyy 12 years in which the date of onset over Kerala has been on or before 18 May.
