| Zusammenfassung |
| The present study suggests that aerosols play a major
role in cloud formation and affect significantly the precipitation over a
regional scale. The study reveals that there is a high variability of
aerosol index during a bad monsoon year 2002, indicating an extension of
cycle to more than 100 days from a normal 50 day cycle of absorbing and
non-absorbing aerosols over a tropical urban station Pune. Pre-monsoon of
2002 shows a high loading of coarse-mode aerosols (absorbing dust aerosols)
which indicate vertical and horizontal temperature variations in turn
affecting the seasonal rainfall at a regional scale. Cloud formation highly
depends on aerosol concentration, but the activation process is not
monotonic. The surface meteorological features help to initiate the cloud
process. The surface temperatures were high during the pre-monsoon of 2002
leading to increase of aerosol optical depth as compared to 2001. The effect
of surface wind speed, though, complicated to understand, results in low
values in 2002 with high aerosol optical depth and vice-versa in 2001. |
