Simulation of snow accumulation and melt in the Votkinsk Reservoir catchment using the WRF-ARW model
Russian Meteorology and Hydrology - Tập 40 - Trang 749-757 - 2015
N. A. Kalinin, A. N. Shikhov, E. M. Sviyazov
Proposed is the method of computation of snow accumulation using the prognostic fields of precipitation based on the WRF-ARW mesoscale numerical model of the atmosphere that was tested using the data for 2012-2014. The snowmelt intensity in river catchments was computed by the method worked out by P.P. Kuz’min. This method is based on the solution of the equation of snow cover heat balance under a...... hiện toàn bộ
Short- and Medium-range Prediction of Relativistic Electron Flux in the Earth’s Outer Radiation Belt by Machine Learning Methods
Russian Meteorology and Hydrology - Tập 46 - Trang 163-171 - 2021
I. N. Myagkova, V. R. Shirokii, Yu. S. Shugai, O. G. Barinov, R. D. Vladimirov, S. A. Dolenko
The ways are studied to improve the quality of prediction of the time series of hourly mean fluxes and daily total fluxes (fluences) of relativistic electrons in the outer radiation belt of the Earth 1 to 24 hours ahead and 1 to 4 days ahead, respectively. The prediction uses an approximation approach based on various machine learning methods, namely, artificial neural networks (ANNs), decision tr...... hiện toàn bộ
Operative short-range hydrodynamic weather forecasting at the points and its efficiency
Russian Meteorology and Hydrology - Tập 35 - Trang 813-816 - 2011
L. V. Berkovich, Yu. V. Tkacheva
Efficiency is discussed of operative hydrodynamic forecasts of meteorological quantities and weather characteristics at the points. Efficiency of hydrodynamic forecasts exceeds that of synoptic forecasts. This allows introducing detailed operative hydrodynamic forecasting of weather at the points.
Dangerous fogs on the territory of Georgia
Russian Meteorology and Hydrology - Tập 37 - Trang 106-111 - 2012
E. Sh. Elizbarashvili, O. Sh. Varazanashvili, N. S. Tsereteli, M. E. Elizbarashvili, Sh. E. Elizbarashvili
The statistical structure of dangerous fogs with the visibility of less than 50 m is studied using the observation data of 50 meteorological stations in Georgia for the period of 1961–2006. The contribution of dangerous fogs to the total number of foggy days is estimated. The number of days with dangerous fogs and their duration in different regions of the country are determined and the empirical ...... hiện toàn bộ
Atmosphere data assimilation system for the Siberian region with the WRF-ARW model and three-dimensional variational analysis WRF 3D-Var
Russian Meteorology and Hydrology - Tập 41 - Trang 808-815 - 2017
R. B. Zaripov, Yu. V. Martynova, V. N. Krupchatnikov, A. P. Petrov
The system of the cyclic assimilation of data on atmospheric conditions used in the West Siberian Administration for Hydrometeorology and Environmental Monitoring is described. It is based on the WRF-ARW mesoscale atmospheric model and on the WRF 3D-Var system of the three-dimensional variational analysis of data. The system is verified when the first approximation data (6-hour forecast) and WRF-A...... hiện toàn bộ
Formation of the fast ice from the seasonal ice and its destruction
Russian Meteorology and Hydrology - - 2013
L. R. Lukin
Application of Radar, Lightning Location, and Numerical Simulation Data to Study the Relationship between Total Lightning Activity and Severe Weather Events
Russian Meteorology and Hydrology - Tập 47 Số 8 - Trang 613-619 - 2022
A. V. Shapovalov, V. A. Shapovalov, V. N. Stasenko, В. Н. Лесев
The Marine Hindcast and Forecast System for Diagnosis and Prediction of Hydrometeorological Characteristics of the Caspian Sea and Forecast Verification Based on Field Measurements
Russian Meteorology and Hydrology - Tập 45 - Trang 639-649 - 2020
V. V. Fomin, N. A. Diansky, E. A. Korshenko, T. Yu. Vyruchalkina
The possibility of using the Marine Hindcast and Forecast System (MHFS) developed at Zubov State Oceanographic Institute for short-term forecasting of hydrometeorological and ice characteristics of the Caspian Sea is demonstrated. The presented implementation of the system is based on the regional nonhydrostatic atmospheric model WRF (Weather Research and Forecast Model) and model of marine circul...... hiện toàn bộ
Effects of Large-scale Modes of Atmospheric Circulation on the Regimes of Temperature and Precipitation in the Arctic
Russian Meteorology and Hydrology - Tập 43 - Trang 1-11 - 2018
D. B. Kiktev, E. N. Kruglova, I. A. Kulikova
The monthly and seasonal anomalies of temperature and precipitation over the Arctic are considered depending on the global and regional patterns of atmospheric circulation. Ñlimate indices are used to identify patterns. The composite analysis allowed identifying the geographic regions where the influence of atmospheric circulation modes on temperature and precipitation is statistically significant...... hiện toàn bộ
Variability of Cloud Parameters from Satellite Data
Russian Meteorology and Hydrology - Tập 44 Số 7 - Trang 452-458 - 2019
Skorokhodov, A. V.
A method for analyzing the variability of characteristics of different cloud types is developed using the results of cloud classification and thematic processing of satellite data. To increase the efficiency of the proposed approach, 16 cloud types were identified during the periods of snow cover absence, and 12 cloud types, in its presence; parallel computation methods on the general-purpose grap...... hiện toàn bộ
