title: Study of formation of the Crimean bora on background of general atmospheric circulation
abstract: Based on the data of standard hydrometeorological measurements of wind speed and direction, the temporal characteristics of Bora phenomena on the southern coast of Crimea for the period from 1990 to 2022 were estimated. Average annual, average monthly values of the number of days with Bora for the study period and the frequency of Bora by months were obtained. To analyze the synoptic conditions for the formation and frequency of the Crimean Bora, the ERA5 reanalysis data on wind speed and geopot
