              Department of Royal Rainmaking and Agricultural Aviation (DRRAA) is accelerating Royal Rainmaking operation to clear the PM2.5 particles in air, effecting people in Bangkok and its vicinity. 

               On 16 January 2019 at 4.30 p.m., Dr. Surasri Kidtimonton, DRRAA Director-General reported through DRRAA Facebook Live on the result of Royal Rainmaking operation to mitigate air pollution in Bangkok and its vicinity as follows:

              According to the upper-air observation in the morning, the relative humidity was in good criteria, but the lift index of clouds was quite low.  Although, the weather condition was poor, DRRAA challenged to make the Royal Rain. 

              At 11 a.m., 2 aircrafts took off to do step 1- Triggering, by making 2 tracks.  One track was started from Phan Thong district of Chonburi province to Bang Nam Priao district of Chachoengsao province to induce rain for the eastern part of Bangkok.  Another track started from Bang Nam Priao district of Chachoengsao province to Ongkharak district of Nakhon Nayok province to induce rain for the western part of Bangkok.  The radar image showed 2 cloud clusters.  The one was above the area of Sumut Prakan province and another one was above the area of Prawet district of Bangkok.  Anyhow, because of the influence of the moderate high pressure from China causing low convective index obstructed cloud development to be able to fall as rain.

              Dr. Surasri Kidtimonton added that on 17 January 2019, DRRAA still stand by to do Royal Rainmaking Operation, to clear the air for Bangkok people.
