FAQs
How do you calculate temperature of rising air parcel? The temperature of a rising air parcel can be estimated using the adiabatic lapse rate, which is the rate at which temperature decreases with height in the atmosphere. On average, this rate is about 6.5°C per 1000 meters (3.3°F per 1000 feet) for dry air.
How do you find the virtual temperature? Virtual temperature can be approximated using the following formula: Virtual Temperature (T_v) = T / (1 – 0.378 * e/p) Where:
- T_v is the virtual temperature.
- T is the actual air temperature in degrees Celsius.
- e is the water vapor pressure in hPa (hectopascals).
- p is the atmospheric pressure in hPa.
What is the virtual temperature of air? Virtual temperature is a temperature equivalent used to account for the effects of water vapor in the air. It represents the temperature a dry air parcel would have if it contained the same total heat content (enthalpy) as a moist air parcel. Virtual temperature is higher than the actual air temperature when there is moisture in the air.

What does 90 degrees with 80 humidity feel like? A temperature of 90 degrees Fahrenheit (32.2 degrees Celsius) with a relative humidity of 80% can feel quite uncomfortable. The high humidity makes the air feel muggy and can hinder the body’s ability to cool itself through evaporation, leading to a sensation of heat stress. It may feel significantly warmer than the actual temperature.
What does 70 humidity feel like? A humidity level of 70% can make the air feel quite humid, but the perception of comfort or discomfort can vary among individuals. It might feel sticky or muggy, and some people may find it less comfortable than lower humidity levels, especially if the temperature is high.
Can the real feel be higher than the actual temperature? Yes, the “real feel” temperature, also known as the heat index, can be higher than the actual air temperature, especially in hot and humid conditions. The heat index takes into account factors like humidity and wind speed, which can make the perceived temperature feel hotter than the actual temperature.
