The analysis of pre-monsoon dust storm over Delhi using ground-based observations

Three major sequential widespread dust events were experienced in the northern parts of India May 2018. A significant impact these pre-monsoon storms on aerosol characteristics over Indian National capital region (NCR) has been studied using remotely sensed ceilometer and ground-based measurements at Indira Gandhi International airport, New Delhi, India. The results show that after each activity, inclusion aerosols loaded free troposphere. Consequently, direct lower atmospheric parameters like increase daily average temperature (by 4–5 K), stepped up (stepped down) diurnal cycles longwave fluxes (shortwave fluxes), recorded within 15 days span. Mainly, adverse meteorological radiation features noticed before first storm (DS1), which pinpoints sudden intrusion NCR, Delhi. However, this extensively impacted vertical loading, surface boundary layer mechanisms, socioeconomic way. Therefore, detailed analysis distribution its interaction with mid-tropospheric processes carried by normalized attenuated backscatter coefficients accompanying radiosonde observation. aloft floating to 3–4 km even shallow rainfall persisted almost same height for next 34 h due low-level clouds. Meanwhile, sub-dust below 1 is formed local also sustains a long time.
