Sharp, short squalls during comparatively calm winds from May to November in Malaya.
Industry:Weather
Sediment particles in the size range of 1/256 to 1/16 mm (or 0. 0039 to 0. 0625 mm). Traditionally, sediment particle sizes in the silt-sized range are defined by their sedimentation diameter.
Industry:Weather
Sea level measured relative to a local tide gauge benchmark. Changes include both local vertical land movements and absolute sea level changes.
Industry:Weather
