A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
Highest heat index: In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F). [ 201 ] Highest temperature with 100% relative humidity : A temperature of 34 °C (93 °F) with 100% relative humidity in Jask , Iran , on 21 July 2012.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
As a two-part measurement, heat index can be measured using charts or online calculators to explore the difference between the two figures and the amount of danger that heat index represents. A ...
In the sun, in the shade, on a rock, in a glade. For every different way there is to experience heat — in the sun, in the shade, on a rock, in a glade — there is a scientific debate about how ...
The calculated heat sums, which are based on data from weather stations or from climate models, differ in that they are too low compared to the actual values in the vineyards. The index does not take into account e.g. thermally favoured hillsides where temperature values may be higher by about 1.5 °C to 2 °C.
NWS Heat Wave Safety Tips: Stay safe with these recommendations • Stay hydrated: Make sure to drink plenty of fluids. • Seek cool shelter: Opt for an air-conditioned room to stay comfortable.
It is touted as one of the hottest cities in the country; in the summer season of 2011 Cabanatuan reached its hottest temperature at 39.8 °C, also the hottest in the Philippines in that same year, and on June 4, 2015 PAGASA reported a 53 °C (127 °F) heat index for the city, which is the hottest yet recorded.
