LASER-RADAR OBSERVATION OF THE FOG CAUSED BY YAMASE WIND FROM THE OKHOTSK SEA

A Mie scattering laser radar with a powerful flashlamp-pumped dye lase r has been developed to measure ''Yamase'' fog which is caused by very cold air intrusion as a result of Okhotsk. high pressure. The inner s tructure of the ''Yamase'' fog-height profile, horizontal distribution , speed, thickness of the fog layer and its time development, periodic movement and dominant periods were observed and analyzed for the firs t time by laser radar of our institute.
