The extreme climate in the Gulf, measured against the Wet Bulb Global Temperature and the Humidex
system, makes working at almost any time of day or night in July, August and the first half of September dangerous, McGeehan said.
The humidity index, referred to as humidex
(Masterson & Richardson, 1979), and apparent temperature (Meng, Williams, & Pinto, 2012; Steadman, 1984) were also calculated to create two additional independent variables for analyses to consider how the combined temperature, relative humidity, and air feels outside; we used this calculation to determine the likelihood of a crime occurring when the humidex
and/or apparent temperature values were high, and thus known to cause discomfort.
The statement added:"We have received constructive feedback from HRW on the Humidex
An analysis of the weather in Doha last summer has also shown that workers on World Cup construction projects were in danger, despite the more advanced system used by the tournament organiser, Humidex
, which measures safety levels of heat and humidity.
Every decedent was assigned daily mean humidex
values for the day of death (case day) and for all occurrences of the same weekday within the same calendar month (control days).
Additionally, EHEs have been defined using biometeorological indices that utilize ambient temperature and other relevant weather parameters; widely used examples of such indices are wet-bulb globe temperature (Budd 2008), apparent temperature (heat index) (Rothfusz 1990), humidex
(Vaneckova et al.
Este criterio incluyo los indices Humidex
(Weather Service of Environment Canada, 2001) y Termo-higrometrico (THI) (Thom, 1959) y Termo-anemometrico (P) (Siple y Passel, 1945; Capelli de Steffens et al.
Existen en la actualidad varios indices de confort termico, ya sean para condiciones de verano o de invierno; algunos de los mas conocidos son: Humidex
(Weather Services of Environment Canada, 2001), Temperatura Aparente (Steadman, 1984), Enfriamiento por efecto del Viento (Siple y Passel, 1945) o el de Temperatura Equivalente (Quayle y Steadman, 1999).
1) In Quebec, extreme heat is defined as a temperature [greater than or equal to]30[degrees]C and a humidex
value [greater than or equal to]40 (2) and heat wave definitions vary according to region (maximal and minimal temperature thresholds are [greater than or equal to]31[degrees]C and [greater than or equal to]18[degrees]C; [greater than or equal to]33[degrees]C and [greater than or equal to]20[degrees]C for at least 3 days for Eastern Townships and Montreal/Laval respectively).
To capture thermal sensation, we use two terms: quadratic humidex
([degrees]C) and quadratic wind speed (km/hour), as well as their interaction to capture the cooling effects of the wind.
The weather bureau also said the humidex
may climb into the 30s.
A heat advisory is declared when a humidex
of 36 or more is forecast for at least two consecutive days.
