Changes in climatic conditions in the Gulf of Ob region

Abstract

The article describes weather conditions characteristic of the quasi-homogeneous climatic region of the Gulf of Ob, lists the main oil and gas condensate, gas condensate, and gas fields, as well as specifying the main requirements for the organization of a full-scale monitoring of weather conditions in the selected region. Climate changes were analyzed using reports on the weather conditions of different regions of the Russian Federation in 2017–2021, prepared by the All-Russian Research Institute of Hydrometeorological Information–World Data Centre. The data analysis revealed primarily positive deviations of the mean monthly temperature from the norm. A positive temperature anomaly was observed in 83% of cases. The climate in the Gulf of Ob region has been getting drier and colder in winter these past five years, which complicates winter navigation. Over the past five years, drier weather has been observed in 50% of cases.
