Association of cloud bursts with forest fires

In news

A recent study has found a connection between the formation of the tiny particles, the size of a cloud droplet on which water vapor condenses leading to the formation of clouds and forest fires. 

About the study
  • The quantity of such particles called the cloud condensation nuclei (CCNs) were found to have peaks associated with forest fire events.
  • Scientists from Hemvati Nandan Bahuguna (HNB) Garhwal University and IIT Kanpur jointly measured the activation of cloud condensation nuclei and studied its impact on high altitude cloud formation and complexity of local weather phenomenon under the influence of different weather condition in the ecologically sensitive regions of Central Himalayas for the first time.
  • Cloud condensation nuclei (CCN), which can activate and grow into fog or cloud droplets in the presence of supersaturation (SS) was measured by a droplet measurement technology’s (DMT) CCN Counter in the pristine Himalayan region at Himalayan Clouds Observatory (HCO), Swami Ram Tirtha (SRT) Campus of Hemvati Nandan Bahuguna (HNB) Garhwal University, Badshahithaul, Tehri Garhwal, Uttarakhand, India.
  • This observation was carried out under a Climate Change Programme Division, Department of Science & Technology (DST) funded project in collaboration with Hemvati Nandan Bahuguna (HNB) Garhwal University and IIT Kanpur, where the variation of CCN was reported on diurnal, seasonal, and monthly scale.
Significance
  • This research will be helpful in source allocation of pollutants reaching the high-altitude regions of Garhwal Himalaya.
  • Also, it will provide the better understanding for the cloud formation mechanism and weather extremities over this region.
