The Marine Hindcast and Forecast System for Diagnosis and Prediction of Hydrometeorological Characteristics of the Caspian Sea and Forecast Verification Based on Field Measurements

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 circulation INMOM (Institute of Numerical Mathematics Ocean Model). The system performance is assessed for the period from January 1 to March 31, 2017 by comparing the forecasts of hydrometeorological characteristics with observational data from hydrometeorological stations. The quality of reproducing sea ice characteristics based on ESIMO objective data is also evaluated.
