Skew T Flashcards
How do you find the CCL?
Take the surface Td up sat mixing ratio until it intersects with the temperature profile
How do you find the cloud base (LCL)?
From surface T bring it up dry adiabat. Bring surface Td up sat mixing ratio. Where they meet is cloud base.
How do you find the LFC?
From your LCL, go up the saturation adiabat until you intersect the temp profile
How do you find the EL?
From the LFC, follow saturation adiabat until it intersects the temp profile
How do you find CAPE?
Goes from the LFC to the EL hugging the temp profile.
How do you find CIN?
From the LFC, it is the area between saturation adiabat and temp until you hit the LCL. Then it is the area down the dry adiabat and temp.
How do you find the Tv?
From the Td, go down the saturation mixing ratio to find w. Then using temp at same pressure, use formula: Tv=T+w/6
How do you find the wet bulb temperature?
From the level, find your LCL, then bring that down the saturation adiabat to the same level.
How do you find the potential temperature?
From the level, bring the temp down the dry adiabat to 1000hPa
How do you find the equivalent potential temperature?
From the level, find the LCL. Then go up the saturation adiabat until parallel with dry adiabat. Bring down the dry adiabat to 1000hPa.
How do you find the potential wet bulb temperature?
From the level, find the LCL. Then bring it down the saturation adiabat to 1000 hPa.
How do you find the mixing ratio?
Using Td, find what mixing ratio you are at.
How do you find the saturation mixing ratio?
Using temperature, find what mixing ratio you are at.
How do you find the vapor pressure?
Using Td, follow the isotherm to 622hPa to find e. It is the mixing ratio number but in hPa.
How do you find the saturation vapor pressure?
Using T, follow the isotherm to 622 hPa to find e(s). It is the mixing ratio number but in hPa.
