Department of hydrometeorological research of the Caspian sea

The main tasks are:

Methodological guide to the organization and conduct of hydrometeorological monitoring of the Kazakh sector of the Caspian sea.

Development of methods for marine forecasts and regulatory documents.

Issue of short - and medium-term, specialized marine forecasts, as well as long-term forecasts of fluctuations in the level surface of the Caspian sea, reviews of overburden events and ice conditions in the Caspian sea.

Completing and maintaining a database of operational data on the main hydrometeorological characteristics of the Caspian sea and the Caspian region.

Performing research on hydrometeorological problems of the Caspian sea and the Caspian region.

Participation in international projects on the problems of the Caspian sea.

Apply method:

Calculations of the level surface and wind currents are performed using the Danish MIKE 21 technology adapted to the conditions of the Caspian sea, based on numerical forecasts of wind fields and atmospheric pressure obtained in accordance with the license agreement with the European center for medium-term weather forecasts (great Britain), as well as information received from Kazakhstan stations and posts and interstate exchange stations.

Forecasts of the wave situation are made using the statistical method of wave prediction, as well as on the basis of the SWAN wave spectral model adapted to the conditions of the Caspian sea. The input parameters are wind field data from the European center for medium-term weather forecasts with a grid step of 0.25 o by 0.25 o.

The forecast of overburden situations is based on the developed hazard criteria.

Reviews of the ice situation are made on the basis of Hydrometerological monitoring data and analysis of satellite images.

Studies of the hydrometeorological regime are carried out using traditional statistical and hydrological methods.

Personnel potential

Employees of the Department have many years of experience in interdisciplinary research on the Caspian problem, including electronic mapping, hydrometeorological surveys, modeling of waves and flooding of the Caspian sea coast. Specialists were trained at the Danish hydraulic Institute on monitoring and modeling of hydrodynamic processes, and also improved their skills in the training centers of WMO, UNESCO, IOC, etc. The Department consists of a specialist with a PhD degree, two specialists are trained in the doctoral program of RSMU (Saint Petersburg, Russia) and al-Farabi Kazakh national University (Almaty, Kazakhstan).

Manufactured products:

Forecasts of hourly fluctuations in the Caspian sea level with a lead time of 120 hours for any area at the request of the customer in tabular and graphical form.

 

Wave forecasts for various sections of the Caspian sea in tabular or graphical form.

 

Weekly Bulletin on the Caspian sea. Includes a 5-day sea level forecast at various locations, maximum, minimum, average water levels, and charts of sea level progress over the forecast period, as well as a forecast of run-up events indicating their location and time of occurrence. In winter, a description of the ice situation on the Caspian sea. The Bulletin contains a satellite image received from the NOAA or MODIS station. It also describes the state of the water surface for the previous period.

 

Weekly newsletter for the excitement on the Caspian sea. Includes a forecast of wave height and period, as well as wind speed and direction in various parts of the Caspian sea.

 

Weekly reviews of the ice situation in the Caspian sea. A satellite image, a General description, and a table with the main elements of the ice regime based on data from Russian and Kazakh stations and posts are placed.

 

Information about the hydrometeorological regime (sea level, waves, ice conditions, water and air temperature, currents, wind).

Probabilistic characteristics of the main elements of the hydrometeorological regime of the Caspian sea.

Results of research on the state of the Caspian sea in various areas of the Kazakh sector of the Caspian sea and the main ports.

The number of forecast points and their location may change at the request of the customer.
