  • A critical aspect of the August 2007 heat wave was the observed variability in heat and humidity across the different geographic regions of North Carolina. The highest maximum temperatures occurred most frequently in the Piedmont and Sandhills
  • regions, while minimum temperatures were exceptionally high along the coast. The broad-scale pattern of heat can be tied to adiabatic warming associated with subsidence downstream of a persistent upper-level ridge centered over the Mississippi River Valley
  • . Regional to local variations in the heat and humidity across North Carolina are linked to upwind sensible heat fluxes associated with major soil moisture deficits, adiabatic warming connected with downsloping winds off the Appalachian Mountains
  • , and the depth of the mixing layer. Along the coast, the pattern of heat and humidity was tied to the positioning of a mesoscale thermal trough and the presence and strength of the sea-breeze circulation.

  • In the analysis of the potential of applying models to estimate threat of heat waves in Poland up to the end of the 21st century, two discrepant climate change models : the MPI-M-REMO-ECHAM5 and DMI-HIRHAM5-ARPEGE have been used. In this regard
  • , the maximum air temperature was analysed. The accepted definition of a heat wave was 3 and 5 consecutive days of temperatures ≥30°C. According to the more realistic ARPEGE model, after 2040, the number of 3 day heatwaves will rise by 370% and after 2070 - 460
  • %. In Warsaw, the extent of possible mortality rates due to cardiovascular disease in heat waves amounted to +134% in the period after 2070 according to the ARPEGE model.

  • This paper discusses the results of an experiment whereby all the major radiation and energy fluxes were measured/estimated for a mature tea canopy at Kericho, Kenya. The fluxes include incoming short-wave radiation, terrestrial radiation, latent
  • heat flux and the sensible heat fluxes between the canopy and the air and that into and out of the soil. The largest proportion of net radiation was consumed by the latent heat flux. Advection was found to be minimal.
