Brown lines
Left
Right
What is an isotherm?
Lines of equal temperature
Isotherms are labeled in degrees fahrenheit or celsius?

Dry adiabats are the slightly curved, solid, (what color) lines that slope from the lower (left or right) to the upper (left or right).
Brown Lines
Right
Left
What do dry adiabats indicate?
They indicate the rate of temperature change in a parcel of dry air rising or descending adiabatically
Saturation adiabats are the slightly curved, solid, (what color) lines sloping from the lower (left or right) to the upper (left or right).
Green Lines
Right
Left
What do saturation adiabats indicate?
Saturation adiabats represent the rate of temperature change in a rising parcel of saturated air
Three vertical staffs along the right side of the chart for use in plotting what?
Upper-wind data.
What is the height at which a parcel of air lifted dry
adiabatically until saturated and then moist adiabatically thereafter, would first become warmer (less dense) than the surrounding environmental air.
The level of free convection (LFC)
True or False: The Convection Temperature is the surface temperature that must be reached to start formation of
convective clouds by heating of the surface air layer.
True
What is the convection condensation level (CCL)?
Is the height at which a parcel of air, if heated sufficiently from below, will rise dry adiabatically until it is just saturated.
What is the Lifting Condensation Level (LCL)?
The height at which a parcel of air becomes saturated when it is lifted dry adiabatically.
What is the wet-bulb temperature?
Is the lowest temperature to which a volume of air at
constant pressure can be cooled by evaporating water into it.
