“…They act as energy sinks in the early summer and energy sources in the fall. The warming of the northern lakes during the spring and early summer tends to occur in the shallower areas first, leaving a pool of cold water in the deeper areas, which is similar to studies of Lake Michigan (Beletsky and Schwab 2001). In the fall, the cooling starts from the shallower areas, particularly in the Great Slave Lake.…”

It is well known that large lakes can perturb local weather and climate through mesoscale circulations, for example, lake effects on storms and lake breezes, and the impacts on fluxes of heat, moisture, and momentum. However, for both large and small lakes, the importance of atmosphere-lake interactions in northern Canada is largely unknown. Here, the Canadian Regional Climate Model (CRCM) is used to simulate seasonal time scales for the Mackenzie River basin and northwest region of Canada, coupled to simulations of Great Bear and Great Slave Lakes using the Princeton Ocean Model (POM) to examine the interactions between large northern lakes and the atmosphere. The authors consider the lake impacts on the local water and energy cycles and on regional seasonal climate. Verification of model results is achieved with atmospheric sounding and surface flux data collected during the Canadian Global Energy and Water Cycle Experiment (GEWEX) program. The coupled atmosphere-lake model is shown to be able to successfully simulate the variation of surface heat fluxes and surface water temperatures and to give a good representation of the vertical profiles of water temperatures, the warming and cooling processes, and the lake responses to the seasonal and interannual variation of surface heat fluxes. These northern lakes can significantly influence the local water and energy cycles.

“…Csanady (1977) described a simple conceptual model that explained the generation of upwelling events in the pelagic part of a lake and compared the modelling results with observations in Lake Ontario. Beletsky and Schwab (2001) achieved a reliable description of the annual cycle of circulation and thermal structure of Lake Michigan using an adapted version of the Princeton Ocean Model. Upwellings in the centre of the cyclonic circulation in Lake Issyk-Kul were studied using in situ temperature data, dissolved oxygen concentrations and estimates of velocities of geostrophic currents and ascending water masses (Romanovskiy and Shabunin 1981).…”

Cyclonic circulation and upwelling in Lake Baikal

We investigated upwelling events in the pelagic area of Lake Baikal that developed during summer stratification (July-November) using a combination of in situ and satellite observations. These upwellings appear in the centres of local cyclonic macrovortices with compensatory downwelling located on their periphery in coastal areas. The average duration of upwelling events was 5 weeks, with an observed maximum of 16 weeks. The most stable upwellings in Southern Baikal and over the Academician Ridge covered areas of up to 4,400 km 2 (59 % of Southern Baikal's surface) and 1,550 km 2 , respectively. Water was ascending in the upwelling zones at velocities of 1 9 10 -4 to 1.2 9 10 -2 cm s -1 . Temperature differences of 1-4°C and 2-13°C were observed between the downwelling and upwelling zones in the epilimnion and metalimnion, respectively. On the surface of the lake, water temperature can drop 4-7°C for water ascending from depths of 10-75 m, but the observed thickness of the layer within which water was ascending reached a depth of 280 m in August-September and 380 m in October; i.e. the ascending water included the entire upper layer (0-300 m). Geostrophic currents reached up to 24-38 cm s -1 on the boundary between up-and downwelling zones (usually 5-7 km offshore), but did not exceed 6-10 cm s -1 in the centres of upwelling zones.Comparison with other large lakes of the world is carried. This study is important for understanding the upwelling process that develops in Lake Baikal during summer stratification and can influence the heterogeneity of nutrients and primary production.

“…The most challenging task for the modelling of enclosed seas like the Caspian Sea is to properly represent the annual thermal cycle, since the thermal regime changes from an entirely thermally mixed one in winter to a strongly stratified one in summer (see Beletsky and Schwab (2001), who detected the same sequence in the case of Lake Michigan). Our simulations with the HYCOM Caspian Sea model were able to reproduce the following main features of the Caspian Sea thermal structure.…”

“…It is a fertile inland sea located between vast deserts of Central Asia, extensive northern plains and the Caucasian high mountain range. Large uncertainties exist with respect to climate change in this zone of sharp transition between climates of the neighbouring Euro-Mediterranean, Siberian, Indian Ocean and Central Asian domains (Bengtsson, 1998;Arpe and Roeckner, 1999;Arpe et al, 2000;Özsoy, 1999;Özsoy et al, 2001).

Abstract. The wind-and buoyancy-driven seasonal circulation of the Caspian Sea is investigated for a better understanding of its basin-wide and mesoscale dynamics, mixing and transport. The model successfully reproduces the following basic elements of the circulation: the southward-flowing current systems along the eastern and western coasts, the upwelling along the eastern coast, the cyclonic circulation in the Middle Caspian Sea (MCS), especially in winter, and the cyclonic and anticyclonic cells of circulation in the South Caspian Sea (SCS). The observed seasonal variability of sea level and sea surface temperature (SST) is well reproduced. Mesoscale structures, not always evident from hydrographic observations, are identified.
