Trajectories and depth of cyclones entering Primorsky Krai.

Abstract

To study activities of various types of cyclones entering Primorsky Krai we analyzed their movement trajectories and depth. Besides, we studied the trajectories of airborne particles for the period before arrival of cyclones, which resulted in precipitation. Dataset history for 2002–2013 was compiled to analyze cyclone activity and depth for the area between 40–50° N and 130–140° E, including the territory of Primorsky Krai and part of the water area of the Sea of Japan. Depending on their generation places and trajectories, seven cyclone types were singled out. Each of them has annual and seasonal dynamics depending on number and depth. Several maps showing back trajectories of airborne particles were compiled to analyze air mass movement in the cyclones that resulted in precipitations in Primorsky Krai. The maps were drawn using HYSPLIT software. Each trajectory is characterized by weight of particles depending on time when airborne particles concentrated in any of related sectors. Weight coefficients allowed analyzing variability of airborne particle transport depending on basic cyclone types. The datasets and survey results are planned to be used while analyzing chemical composition of precipitation depending on cyclone origin (types)
