Air temperature controls
Formula to convert C to F
What is (C*1.8)+32
A byproduct of deposition when you cool the temperature of an object below the dew point temp of the surrounding air and the air temperature is below freezing
What is frost
Colder air aloft- parcels move (faster or slower), (instability or stability)
faster, instability
What is a higher relative humidity
Absorbed heat becomes latent heat when being absorbed
What is evaporation
The four air temperature controls from place to place
What are differential heating of land and water, ocean current temperatures, elevation and latitude/geographic position (exposure)
A byproduct of condensation when you cool the temperature of an object below the dew point temperature of the surrounding air and the air temperature is above freezing
What is dew
Solar heating, horizontal (colder to warmer) heating of airmass as it moves over a warmer surface, dynamic lifting of air, surface convergence air, radiative cloud top cooling from thunderstorms in adjacent areas
What enhances unstable air
Comparing the weight/mass of water vapor volume per parcel of air to the dry air in the parcel
What is the mixing ratio
2 PART
If the relative humidity is higher and the air temperature is warmer, sweat occurs (faster or slower) with (more or less energy)
What is slower, more (think steam not sauna)
When is July 1-June 30
Condensation nucluei (and condensation) + saturation/100% relative humidity= this
What are clouds
2 PART
When the 3.3 < ELR < 5.5, same scenario but with unsaturated air
What is conditionally unstable , absolutely stable
As air temperature increases, relative humidity does this (assuming moisture levels are the same)
What is increases (inverse relationship between air temperature and relative humidity)
Biometerological application based on air temperature and wind speed
What is the wind chill index
The type of degree day (HDD or CDD) when the air temperature is above 65 degrees
What is a cooling degree day
Cooling fog where rising water vapor+ cool air condenses/rises with the air being warmed below. Most common in lakes/barton springs
What is steam/evaporation fog
Air temp- 3.3 degrees F, used in clouds
What is the Moist Adiabatic Lapse Rate (MALR)
A ratio of the air's actual water vapor/moisture content compared to the amount of water vapor required for saturation at a given temperature. Tells only how close we are to saturation.
What is relative humidity
A more realistic biometerological application based on air temp, relative humidity, sun/solar heating and wind speed
What is a wet bulb globe temperature
In Austin, which (heating or cooling) requires more energy/is more unpredictable
What is heating/HDD
Ocean fog near the shore/moving inland. In the morning, on the shore, the clouds are over the ocean and land is warming. At night the clouds are over the city and the land is cooling. Most common on west coast. Warm moist air is being blown over a cold surface.
What is advection (cooling) fog
Comparing the temperature of a parcel of air as it rises and falls in the atmosphere to the environmental air temperature
What is atmospheric stability
The location of the air parcel when there is the dew point is lowest
What is to the left
Biometerological application based on air temperature and amount of moisture and is a cumulative process
What is the heat stress index
