The paper reports preliminary results of physioclimatological investigations performed outdoors in the Summer 1996 in Central Poland. The studies dealt with the temporary changes of dry heat exchange (DHE) and skin temperature (Tsk) as well
as thermal sensations in subjects during varying cloud cover. Preliminary results show clear relationships between DHE as well as Tsk and intensity of solar radiation (Kglob). In fluctuated cloud cover significant changes of DHE, Tsk and thermal sensations

The paper presents principles of man-environment heat exchange outdoor which influence human health and well being. The MENEX model was applied for the estimation fo the human heat balance as well as heat load and thermal sensations of man
in different meteorological situations. It was also used for forecasting of thermal conditions and for assessing thermal conditions of work. - (DG)

The ways of incorporation of hydrologic cycle elements into the dynamic-stochastic heat and water exchange climate model are considered. Such approach enables to identify the main sources of precipitation climatologic variability.

) and physiological strain (PhS) are derived from man-environment heat exchange model MENEX―2002. STI evaluates the thermal sensations in man outdoors during light physical activity. HL assesses the loading of the thermoregulatory system in man in a fluctuating
outdoor climate. PhS defines the kind and intensity of physiological processes during adaptation to ambient thermal conditions. - (BJ)
Thermal characterisation of active layer across a soil moisture gradient in the McMurdo Dry Valleys, Antarctica
Here, the AA. present results of a study to characterise soil thermal properties along a soil moisture gradient adjacent to Lake Fryxell in Taylor Valley, Antarctica. The goals were to characterise the thermal characteristics of these relatively wet
gradient of wet to dry soils adjacent to Lake Fryxell from January 2006 to January 2007. They used a numerical model to estimate apparent thermal diffusivity (ATD) and simulate observed temperature time series. Estimated bulk ATD values were consistently
greater in locations of enhanced soil moisture, so lakeside soils were more likely to conducte energy into the subsurface. Increased soil moisture across the landscape would likely increase ATD, allowing for greater heat exchange between the atmosphere

Leaf area index (LAI) of natural vegetation is recognized as the most important variable for measuring vegetation structure over large areas, and for relating it to energy and mass exchange. In this paper, according to the statistical analysis based
on a lot of forest plots, the mathematical models of LAI distribution patterns in the hydro-thermal spaces for 5 coniferous forest types in China were established.
conditions had a greater effect on the thermal conditions at sites where water depths were close to the maximum ice thickness. The short ice contact times at these sites are important to the thermal state of permafrost, as only minimal heat exchange
thermal conditions was determined at 3 monitoring sites. When comparing conditions over the two winters, 2005–06 was characterised by a decrease in ice thickness that limited the extent of BFI and seasonal cooling of the ground. These changes in ice
This paper summarizes the cross-lake variations of meteorology, evaporation, heat fluxes, thermal response, heat content, and physical limnological processes based on 1998 summer and 1998/1999 winter over-lake measurement platforms within the main
-lake section of Great Slave Lake. The long-term objectives of this research include modeling the heat and mass exchange components, assessing potential climate change impacts, and quantifying the interannual variabilities. These analyses

The paper presents some results of bioclimatic research performed over the territory of Poland with the use of the human heat balance method. The recent studies are based on various models of heat exchange, Budyko's model for stationary
and Błażejczyk's MENEX model for nonstationary conditions of heat exchange. Presented studies concerned to different spatial scales. - (DG)
