Web9 de abr. de 2024 · Sometimes, if we talk about relative humidity, it can be misleading as well. If a region has a temperature of 40° with a dew point of 40 will lead to 100% relative humidity whereas, on the other hand, a region with a temperature of 80° with a dew point of 60 will lead to having 50% humidity. WebWhen the temperature is 30 °C (86 °F) and the dew point is 15 °C (59 °F), the humidex is 34. If the temperature remains 30 °C (86 °F) and the dew point rises to 25 °C (77 °F), the humidex rises to 42. The humidex is higher than the U.S. heat index at equal temperature and relative humidity. The humidex formula is as follows: [7] [8] where WebVarious types of apparent temperature have been developed to combine air temperature and air humidity. For higher temperatures, there are quantitative scales, such as the heat index.
