How to calculate a 'Feels-Like' temperature using OpenWeatherMaps Raw feels like.js This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. With most any breeze, "Feels Like" is usually a lower number than heat index due to evaporative cooling of your skin by the wind. The BOM's "feels like" metric is calculated as follows: A T = T a + 0.33 0.7 4.00. where: Ta = dry bulb temperature (C). We have a combination of Heat Index and Wind Chill Factor: at temp <50 F (10 C) we use wind chill, and at temp >80 F (26.6 The humidex ("Hyu-mah-deks") is a temperature index used by Canadian meteorologists to describe how hot the weather feels to a person, by adding the effect of heat and humidity. A simple measure of how a temperature of 85 degrees Fahrenheit, for example, will likely feel different in Houston, Texas versus Los Angeles, California is the heat index. Wind chill "feels like" formula in column F is: =35.74 + 0.6215*D2 - 35.75*E2^0.16 + 0.4275*D2*E2^0.16. El Paso, TX7955 Airport RdSanta Teresa, NM 88008(575) 589-4088Comments? The wind chill is typically always lower than the temperature of the air because wind increases how quickly moisture evaporates from the skin and serves to move heat away from the body. #fca_qc_quiz_58020.fca_qc_quiz button.fca_qc_next_question:hover { Please note that archive episodes of this podcast may include references to Everyday Einstein. 78F at 80% humidity levels.
