Sentences with phrase «wet bulb temperatures by»

Professor Eltahir and his colleagues in 2015 examined conditions in the relatively wealthy Gulf region, and predicted potentially lethal wet bulb temperatures by 2100.

Spray droplets are cooled to their wet bulb temperature by evaporation before falling back into the sea, thereby transferring a huge amount of heat from sea to air.

Not exact matches

The new analysis is based on recent research showing that hot weather's most deadly effects for humans comes from a combination of high temperature and high humidity, an index which is measured by a reading known as wet - bulb temperature.

The study shows that by century's end, absent serious reductions in global emissions, the most extreme, once - in -25-years heat waves would increase from wet - bulb temperatures of about 31 C to 34.2 C. «It brings us close to the threshold» of survivability, he says, and «anything in the 30s is very severe.»

Wet bulb globe temperature is the heat stress metric used by the International Organization for Standardization, and it has well - validated thresholds for when humans can safely work, giving it advantages over alternative metrics such as heat index, said study co-author Chao Li, a hydroclimatology scientist at the University of Victoria in Canada.

I suspect that although currently the probability of lethal wet bulb temperatures, or catastrophic rain events are very low, because of the shapes of the curves and «the Statistical parameters are surprisingly predictable, and weather statistics is systematically influenced by the physical conditions present» that their relative increase and risk are much higher than most people appreciate.

I don't understand how mammals could have survived for 100 million years given the supposedly fatal wet bulb temperatures quoted by ATTP.

Using global climate models, the researchers mapped current and projected future «wet - bulb» temperatures, which reflect the combined effects of heat and humidity (the measurement is made by draping a water - saturated cloth over the bulb of a conventional thermometer; it does not correspond directly to air temperature alone).

Today, the summer temperature varies widely over the Earth's surface, but wet bulb temperature is more narrowly confined by the effect of humidity, with the most common value of approximately 26 — 27 °C and the highest approximately of 31 °C.

The wet - bulb temperature is the temperature an air parcel would have if it were cooled to saturation at constant pressure by evaporating water into the parcel.

For example, sunlight on a choppy, well - mixed sea is likely to primarily heat the water, where sunlight falling on a stagnant pond goes mostly into evaporation, since the water temperature is limited by the wet bulb temperature.
