Microclimate of «Sochi-2014» sport venues
7 Enhanced observational network; Nowcasting tools; High-resolution NWP models and EPS; Regional data assimilation; Means of NWP output interpretation and delivery (new parameters and products, visualization etc); High-resolution verification system; Training Primary meteorological needs for Sochi-2014:
Observational network in the region of the Games None of practically realizable near-surface atmospheric monitoring networks can be representative enough given the complexity of the region and high Olympic demands. In situ observations are mostly concentrated along the coast. Vast sea area from one side and nearby high mountains (up to 3 km and more) on another side of Krasnaya Polyana are data sparse areas. Nevertheless, today situation is substantially better than 1-2 years ago, and enhancement of the network will continue. + In general about 30 near-surface automatic stations to be added to enhance the observational network in the region. + New Doppler radars in Sochi and other parts of the region; + Other ways to enhance the observational network are looked into (wind and temperature profilers; moored sea buoys; more frequent sounding at the nearest aerological stations; etc)
Supplementary network of AMS on the towers of mobile communication should be developed in the region in cooperation with private companies Wind sensor Data processor Precipitation gauge Temperature and humidity sensors AMS should be accompanied by rotatable web-cameras.
Roshydromet plans to provide access to the enhanced set of regional weather observations for the partners involved in the meteorological support of the Games. Development of comprehensive set of observational data for purposes of forecasting, data assimilation and forecast validation is one of the key elements of meteorological support of the Games 50 km Doppler radar Mountain cluster of sport venues Coastal cluster of sport venues Filled circles – locations of AMS.
«Vancouver-2010» region «Sochi-2014» region In comparison with Whistler the mountain cluster in Krasnaya Polyana is situated substantially closer to the sea and there is less space for deployment of upstream land- based observational network. From the point of view of meteorological needs and goals Sochi-2014 Olympic project has much in common with Canadian Vancouver Olympic project SNOW-V10.
Existing radar facilities in the region Today 3 radars МРЛ-5 work in the region – Anapa, Sochi (Adler) and Krasnodar. Unfortunately, their technical state, locations and capabilities of digital data processing system dont meet the requirements of the meteorological support of the Olympics. Cardinal modernization of the radar network in the region is needed. Integral reflectivity for meteorological radars МРЛ-5 in Anapa, Adler and Krasnodar for the layer 1-2 km (February 2010)
Radar network modernization In September 2008 Russian government approved the Federal task program "Modernization of the unified system of air traffic organization of the Russian Federation ( )". According to the program about 140 new-generation Russian-made Doppler radars should be installed in various parts of the country, including Sochi region, and replace МРЛ-5 radars. In 2011 МРЛ-5 radars should be replaced by new Dopplers in the airports of Anapa, Krasnodar and Adler. In 2012 new radar should be installed in the area of Gelendjik airport.

Doppler radar in Sochi: state of affairs At the end of 2010 there were field tests of the new radar equipment developed and produced in the framework of the Federal task program "Modernization of the unified system of air traffic organization of the Russian Federation ( )". Although the test results are quite good, in general this process has been evolving with delays. To not put the preparations to the Olympics under the threat of delays it was decided at least for Sochi to buy a radar of external vendor. Vaisala Doppler radar WRM200 was bought in December This new radar will be installed on Akhun mountain in Sochi. The data flow from the radar is expected to be organized by the winter 2011/2012.
Radar position on Akhun mountain Location: 43 о 3252,6 ״ N, 39 о 51 ׳ 05,0 ״ E, Altitude – 646 m. From the point of view of coverage this position is the best in the region of Sochi. Installation of radar antenna on a 30-meters tower will allow to get rid of shading by the trees. There are no obstacles in the western and southern sectors. In eastern and north-eastern directions horizon shading will not exceed 1-2 degrees in vertical. Thin lines designate 500 m topography level; Bold brown lines – 1000 m topography level.

Wind - AP1000 Radar Wind Profiler (Scintec Corporation, U.S.A.); Temperature/Humidity – to be decided (negotiations with RPG GmBh, Germany) Roshydromet plans to station the profilers on mobile platform. Some flexibility in location of profilers (e.g. their location up-stream of the venue) might enhance their forecasting capabilities. Profilers
Nowcasting tools for Sochi Current experience of nowcasting in Russia is very limited and associated with plain areas (as in general observational coverage is quite modest). Mountain nowcasting is a brand-new area for Roshydromet (High requirements for the weak point of the Service). By now Roshydromet does not have firmly established nowcasting graphical tools. Existing technologies are not comprehensive and mature enough to meet the Olympic demands. Options: GIS-Meteo, AWIPS, Ninjo, … ?
Numerical weather prediction Complexity of Sochi region stimulates application of high- resolution modeling. By 2014 horizontal grid step about 1 km seems to be a realistic level of model resolution. Key areas to be addressed: data assimilation, predictability and uncertainty, physics at high resolution, validation of high resolution modeling, numerical challenges at high resolution, utility of model configurations that have potential in nowcasting. High-resolution data assimilation is a necessary prerequisite for meso-scale forecasting. The remote sounding is the main source of meso-scale structures in the initial data for such a modeling. Potential input for assimilation: Satellite radiances (AMSU-A, AMSU-B, AVHRR, IASI, SSMIS); Satellite winds (AMV, ASCAT); Doppler radars; Wind and temperature/humidity profilers Convective-scale multi-model ensemble forecasting might be a new experience of Sochi-2014
In 2007 Roshydromet joined For the period up to 2014 the COSMO goal is to develop a model- system for the short to very short range with a convective-scale resolution to be used for operational forecasting of mesoscale weather, especially high impact weather. The strategic elements to achieve this goal are: – an ensemble prediction system for the convective scale (development of a conserving dynamical core; progression towards a unified turbulence-shallow convection scheme etc); – an ensemble-based data assimilation system for the convective scale (LETKF); – extension of the environmental prediction capabilities of the model; – a verification and validation tool for the convective scale; – an intermediate resolution COSMO version for the provision of boundary conditions; – use of massively parallel computer platforms; – intensified collaboration within and beyond COSMO.

COSMO contributions to Sochi project A COSMO-LEPS (7-km grid spacing) centered around Sochi for a dynamical downscaling of the ECMWF EPS with a forecast range of up to 5 days.The idea is to run the COSMO-LEPS- Sochi for a test period during winter 2012/2013 and in production mode during winter 2013/2014. Deterministic, high resolution COSMO model (2.2 km grid spacing; forecast range up to 24 hours; rapid update cycle) nested into the 7-km COSMO-RU model in Moscow. The model runs should include data assimilation using all available data, including the Doppler radar in Sochi. Extensive work on development of convection-permitting model version is on the way (Some COSMO members already have a substantial experience at convection-permitting resolutions).

Roshydromet is very interested in the international collaboration in order to improve its forecasts of winter weather in mountainous terrain Meteorological support of the Games implies both research and practical forecasting. Potentially both types of WWRP projects (Research Development Project and Forecast Demonstration Project), could be relevant.
General goal: To enhance and demonstrate capabilities of modern systems of short-range (up to 1-2 days) NWP and nowcasting in winter conditions for mountain terrain and to assess effect of practical use of this information. Subgoals – to develop and implement: Nowcasting of multi-weather elements (wind speed and wind gust, visibility, precipitation intensity and time) in a region with complex terrain in winter season. New nowcasting products for high impact winter weather events; High resolution modeling for a region with mountain terrain in winter season; High resolution ensemble forecasting of high-impact winter weather events in a region with complex terrain; High resolution remote sensing data assimilation; High-resolution forecast/nowcast verification using remote sensing data.

Radar position in the area of Adler airport Currently: ׳ 06 ״ N, ׳ 07 ״ E, Altitude above sea level – 104 m (at the mountain above Adler airport). Current position has very broad shaded sectors even in the seaward directions. Installation of radar antenna on a 30-meters tower (~20 m higher than today) will allow to get rid of shading due to trees, but will not substantially improve situation in the sector from 325 о to 95 о (in the direction to mountain cluster).

Radar position in the area of Anapa airport Today МРЛ-5 radar is located on the territory of the airport at altitude 60 m. It would be optimal for better coverage to move it 3 km eastward to the nearby hill of 170 m height (see photo below). However, it is difficult to legalize that position. As a result the exact location should be selected on the territory of airport. It is planned to use 30-meters tower for the radar antenna. This will ensure good westward visibility and better than today visibility in North- West and Southern sectors.
Radar position in Krasnodar airport Today МРЛ-5 radar is placed at 9 m height and visibility sector is shaded by the trees and buildings. In general current position has quite poor visibility coverage. Nevertheless, it provides useful information from the area to the north of main mountain ridges. Lifting the radar to the tower can substantially reduce shaded sectors, but firstly it is necessary to get approval from airport management.

Radar position in the area of Gelendjik airport To be installed in Along with new radar on Akhun mountain (Sochi) it can become the second key radar in the region. Location on the top of mountain Ploskaya ( ,8 ״ N, ׳ 49,0 ״ E) at 762 m altitude will ensure high-quality data not only from the Black sea, but from the northern sector. It can be combined with information from Krasnodar radar.
