Weather Calculations 7.0.0

Weather Calculations presents a comprehensive suite of six calculators that facilitate a thorough understanding of various weather phenomena: Heat Index, Wind Chill, Dew Point, Apparent Temperature, Humidex, and Wet Bulb Globe Temperature. This multifaceted tool accommodates both imperial and metric units, including a built-in unit converter, allowing users to input air temperature in Fahrenheit or Celsius and wind speed in miles per hour, meters per second, kilometers per hour, or knots.

Users can compare different models to ascertain how they perceive the weather and explore various scenarios to deepen their understanding of meteorological modeling.

• Heat Index Calculator
  The Heat Index Calculator utilizes models from the US National Weather Service to compute the heat index. It is important to note that this index is defined for temperatures exceeding 80 degrees F (27 degrees C) and relative humidity levels above 40%. Outside these parameters, accuracy may be compromised.
• Wind Chill Calculator
  This calculator leverages both the new (post-2001) and old (pre-2001) Windchill Temperature (WCT) index models from the US National Weather Service. Additionally, it offers the historical Windchill Index in kcal/m²/h. Accuracy is typically maintained for conditions with temperatures below 50 degrees F (10 degrees C) and wind speeds surpassing 3 mph (4.8 kph or 1.34 m/s).
• Dew Point Calculator
  Unlike many of its counterparts, the Dew Point Calculator computes not only the dew point temperature but also deduces the air temperature from a given dew point and relative humidity. It further calculates relative humidity based on air temperature and dew point temperature using the more reliable August-Roche-Magnus model. Accuracy is established for temperatures between 32°F (0°C) and 140°F (60°C).
• Humidex Calculator
  The Humidex Calculator offers a streamlined assessment of how humidity influences perceived temperature. This model is based on data from the Meteorological Service of Canada.
• Apparent Temperature Calculator
  Employing a three-factor model developed by the Australian Bureau of Meteorology, this calculator provides a 'feels like' temperature that integrates humidity and wind chill effects for both high and low temperatures.
• Wet Bulb Globe Temperature Calculator
  This calculator estimates how temperature combines with humidity to affect perceived heat. Users can input temperature and relative humidity to derive the Wet Bulb Globe Temperature index (WBGTI), which includes flag indicators for quick identification of outdoor activity risks, as outlined by USMC standards. This tool relies on approximation methods similar to those employed by the Australian Bureau of Meteorology, assuming typical sunny conditions with light winds. It may overestimate perceived heat on cloudy or windy days.
