in the nighttime, drainage flow occurs along the basin sideslope and advects cold air to the boundary layer over the basin bottom (bbl), intensifying the cooling rate of the layer. a nocturnal cold air lake develops in the basin, attaining a depth nearly equal to the topographical depth of the basin. heat budget analysis of the whole basin surface shows that net radiative flux closely balances ...

52 years of data (1949-2000) from the NCEP-NCAR reanalysis are used to investigate mechanisms involved in forcing and damping of Sea Surface Temperature (SST) variability in the South Atlantic Ocean. Organized patterns of coupled ocean-atmosphere variability are identified using EOF and SVD analyses. The leading mode of coupled variability consists of an SST pattern with a strong northeast-sout...

A strong relationship is observed between synoptic weather systems and atmospheric forcing of the ocean as estimated from buoy measurements made on the North Carolina inner shelf during August and October-November 1994 as part of the Coastal Ocean Processes (COOP) Inner Shelf Study. Synoptic variation (timescales of days to weeks) in the meteorological time series was primarily associated with ...

The surface heat budget in the equatorial Pacific Ocean was investigated through ocean model simulations, both the climatological cycle and the case of the 1994–95 warm event. The dominant processes governing the seasonal cycle of sea surface temperature (SST) vary significantly across the basin. In the western Pacific the annual cycle of SST is primarily in response to net surface heat flux. I...

The causes of wintertime precipitation decrease in the Southern Coast of Caspian Sea (SCCS) compared to its counterpart in autumn, is investigated with the use of synoptic stations daily dataset of SCCS and gridded NCEP/NCAR and NOAA dataset. The structure of atmospheric circulation and synoptic and physical conditions over the Caspian Sea region which are dominate in the winter and autumn prec...

In order to make the prediction of land surface heat fluxes more robust, two improvements were made to an operational two-layer model proposed previously by Zhang. These improvements are: 1) a surface energy balance method is used to determine the theoretical boundary lines (namely 'true wet/cool edge' and 'true dry/warm edge' in the trapezoid) in the scatter plot for the surface temperature ve...

In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...

At the leaf scale, it is a long-held assumption that stomata close at night in the absence of light, causing transpiration to decrease to zero. Energy balance models and evapotranspiration equations often rely on net radiation as an upper bound, and some models reduce evapotranspiration to zero at night when there is no solar radiation. Emerging research is showing, however, that transpiration ...
