Dangerous hydrological phenomena of the Krasnoyarsk Territory and the lead time of their forecast

Abstract

In Russia, there are significant fluctuations in climatic conditions throughout the country, the damage from hydrometeorological phenomena is 80–90% of the total damage of a natural nature. For the territory of the Krasnoyarsk Territory, five types of dangerous hydrological phenomena are characteristic, leading to the occurrence of material damage: traffic jams, ice jams, low low water, floods and floods. The research material was long-term data on fixing dangerous hydrological phenomena with fixed material damage for 30 years. The analysis of dangerous hydrological phenomena was carried out, the stationarity of the time series was checked, and conclusions were drawn about the statistical significance of the obtained trends. Information about the issued forecasts for each hydrological phenomenon is analyzed, information about their lead time is systematized. Research data can be used by institutions and organizations authorized to conduct environmental monitoring in determining regional lists and criteria for hazardous natural phenomena.
