Cloud seeding

Seeding Clouds to Spout Rain

Cloud seeding is a method of enabling inefficient clouds to bring rain, or enhance rainfall from a seedable cloud by introducing seeding material. The secondary effect of evaporation from falling precipitation improves the thermodynamic efficiency of the environment to form fresh convective clouds and more rain. This principle is used to enhance rainfall and reduce […]

Aircraft Probing

Airborne measurements are extremely important for aerosol sampling, measurement of cloud properties, cloud physics, atmospheric chemistry and other scientific needs. Aircraft probing and surveillance enables the observation of upper air phenomena, especially cloud aerosol interaction. The wealth of atmospheric, aerosol and cloud microphysics data generated by aircraft probing can be used in assessing air pollution […]

Pre-earthquake Process and the 2004 Tsunami

The disastrous earthquake-triggered tsunami that occurred 11 years ago on the morning after Christmas was huge by any contemporary standards. The epicenter of magnitude 9.3 quake was located in the Indian Ocean near the west coast of Sumatra and it ruptured the 1000 km long Andaman plate boundary, moving the seafloor 20-10 m vertically upwards, […]
