Features of Air-Lake Interaction in Heat and Water Exchanges over Erhai Lake

Abstract: This paper presents the characteristics of air-lake-land interactions, which arise from the di¤erent thermal properties of lake and land surfaces, as observed at Erhai Lake in Yunnan Province, China. The heat balance over the lake was estimated by using data on the lake surface obtained from the Erhai automatic weather station and solving the surface heat balance equation (HBE) for a mixed layer. Meteorological station data were also used to estimate the long-term heat balance. The surface temperature from in … Show more

“…Finally, it is obvious from Table 2 that deep lakes have longer time delays than shallow lakes; for instance, Lake Valkea-Kotinent and Logan's Dam have water depths of less than 10 m and do not show obvious phase delays. However, Lake Superior and Lake Namu Co have depths of more than 90 m and display phase delays as long as 5 months (Blanken et al 2011;Haginoya et al 2009;McGloin et al 2015;Nordbo et al 2011). Therefore, the phase delay between the net radiation and turbulent energy may be attributable to the lake depth.…”

“…The variations in ice phenology affect the amount of on-lake evaporation, since the lake-ice blocks the water-air interface, and sublimation does not compensate this effect. A deep lake, such as Nam Co, can supply a large amount of heat energy to the atmosphere in the post-monsoon period (Haginoya et al, 2009). Air masses passing over a large, relatively warmer open-water area during winter can lead to heavy snow fall on the downwind shore.…”

“…The availability of remote sensing data allows bulk estimation of changes in water level, area and the lake surface skin temperature (T s ). Studies on the lake effect on the regional water budget suggest that evaporation from one of the largest Tibetan lakes, Nam Co, provides up to 28.4Á31.1 % of the local atmospheric water vapour content during the summer monsoon season , whereas the annual evaporation from Nam Co Lake exceeds annual precipitation and evaporation from the surrounding land (Haginoya et al, 2009). Simulations suggest that the different surface heat and mass budget over lakes could increase the regional precipitation over TP, including snow and rain (Li et al, 2009;Wen et al, 2015).…”
