On January 9 2020 the National Center of Meteorology & Seismology began five cloud seeding flights in the late afternoon.[16] The center was testing a new technique and material developed by Prof. Linda Zou which “elongates the condensation process [inside clouds] as it enlarges the cloud droplets more than the conventional material… This results in larger numbers of water droplets during rainfall amounting to up to triple times the old method.”[17]
