The aim of this study is to compare the bioclimatic comfort conditions of Uşak city between 1990 and 2018. In the first stage, the bioclimatic comfort conditions of the city centre between 1990 and 2018 were determined according to the Physiological Equivalent Temperature (PET) index obtained from the RayMan model by using hourly data of the meteorological station in the city centre; air temperature (°C), relative humidity (%), wind velocity(m/s) and cloudiness (octa).

Epidemiological studies have investigated the short-term effects of meteorological factors and air pollution on the incidence of hand, foot, and mouth disease (HFMD). Several meteorological indicators, such as relative humidity and the diurnal temperature range (DTR), significantly modify the relationship between short-term exposure to temperature and HFMD incidence.

Sunburn injury is common on fruits in due to high solar radiation levels and air temperatures, low relative humidity, and high elevations. The incidence and severity of sunburn depends upon climatic factor, cultivars, hormonal, nutritional and soil moisture. Fruit production losses due to sunburn may be 6 to30 per cent depending on seasons and the type of fruit.

Aerial biomass forms an essential ingredient of air. Air is one of the most essential requirements for the survival of mankind and other animals on this planet. The quality and composition of air change with the change in aerial biomass. Meteorological factors viz. temperature (T), relative humidity (RH) and rainfall (RF) affect the composition of air. Meteorological factors affect the health of people by changing the composition of air we breathe. A study was done to assess the impact of meteorological factors on aerial biomass and hence on health of the people.

This paper aims to quantify the amount of water surface evaporation with special regard to the EWM evaporation pan and to relate the direct measurements to the Penman and other empirical equations. Based on the available 10-minute interval data on the EWM pan evaporation and the data on precipitation for the same intervals, the net water surface evaporation was estimated for the period from July 2010 to October 2012 (excluding the time EWM pan did not function in winter).

Kerala is the region with high humidity and comparatively low solar radiation, there is much scope of uneven and uncontrolled drying of copra. Hence, an attempt was made to develop a sophisticated and advanced forced convection solar dryer. Evacuated tube collector (ETC) was used to generate hot air and used to dry coconuts. It consists of three units: evacuated tube collector, blower and drying chamber. Coconuts (Cocos nucifera) were dried at full load condition in order to evaluate the performance of the developed solar dryer.

Morphological leaf traits can be used to assess adaptive responses of plants to environmental conditions. To assess how the representation of Huperzia serrata leaf traits, such as leaf length (LL), leaf width (LW) and leaf area (LA) response to changes in mean annual temperature (MAT), sunshine duration (SuH), mean annual precipitation (MAP), air humidity (Hu), intraspecific variation of the morphological leaf traits of the species was analyzed along a geographical gradient of Vietnam.

Evaporative cooling system is one of the cooling techniques, but the limitation is that cooling can be done up to wet bulb temperature only, so a study has been taken up to design, develop a two-stage evaporative cooling system. Cooling performance of twostage indirect/direct evaporative cooling system was experimentally investigated. For this purpose, a two-stage evaporative cooling experimental setup consisting of an indirect cooling stage (IDC) followed by a direct evaporative cooling stage (DEC) was designed, constructed and tested.
