Cloud and Rainfall Enhancement (IMAGE) Proceedings of the National Academy of Sciences Caption Cloud and rainfall enhancement over a jojoba plantation in the coastal desert of Oman. Contour colours show atmopheric heating (watts per square meter), wind vectors show winds at 10 m height above ground (unscaled), with vectors colors showing temperature at 2 m height above ground (Kelvins). Black vectors are updrafts and downdrafts associated with the development of a convective cell. Liquid-phase clouds are grey-silver and rainfall is shown as blue-turquoise.
