Roll Circulation

Investigation of roll circulations and its transport characteristics in the atmospheric boundary layer (ABL) is carried out. The case study in Kalmykia, 28 of July, 2007, where the equipment measurements have been conducted by A.M. Obukhov Institute of Atmospheric Physics, is analyzed with the use of WRF-ARW model. The evolution of the circulation with considerable asymmetry in the positive and negative velocity and helicity components is registered. The rolls is sign out by the intensification of the dust picking up and accumulation from underlying terrain, and along with intensive vortices with vertical axis become the significant source of atmospheric pollutants. Captured fine aerosols can be transported by long distances and form the aerosol layers.

The article is devoted to various aspects of the use of unmanned aerial vehicles (UAV) for the study of the atmospheric boundary layer. The characteristics of the atmospheric boundary layer, measured using the UAV, are considered. The types of devices and measuring systems used are presented. The characteristics of measuring systems installed on a fixed-wing aircraft and copter UAVs developed in the A.M. Obukhov Institute of Atmospheric Physics RAS (IAP RAS) are presented. A brief overview of a number of the IAP RAS measurement campaigns is given. The prospects of using UAV in meteorology and atmospheric physics are considered
