Q

the vertical potential temperature profile is used to determine

A

static stability

5
Q

examination of the horizontal ɵ distribution is useful in

A

locating frontal boundaries

6
Q

When diabatic processes are negligible, air parcels are constrained to travel along surfaces of

A

constant ɵ, known as isentropic surfaces.

7
Q

as isentropic surfaces

A

surfaces of constant ɵ

Q

The lowest 1 km is characterized by

A

unsaturated turbulent mixing

9

the temperature of rising and sinking air parcels follows the ………………………………….., meaning that potential temperature is ……………………………for parcels moving in this layer

A

10
Q

In the presence of solar heating, there may even be a slight …………………………………….immediately ……………………the surface, indicated by a small zone where potential temperature………………………………

A

superadiabatic layer, above , decreases with height

11
Q

Surface-based mixed layers usually correspond to the

A

planetary boundary layer

12
Q

Surface-based mixed layers usually correspond to the planetary boundary layer. The mixed layer depth has important implications for

A

air pollution , forecasting surface temperature and wind conditions

A

neutral stability

14
Q

In the midlatitude troposphere, potential temperature typically ……………………….with height.

A

increase

15
Q

The more rapid the increase of θ with height, the more …………………….is the atmospheric profile.

A

stable

16
Q

The equivalent potential temperature is ………………………….for a wide majority of atmospheric flows, and is related to ………………………….

A

conserved, stability

17
Q

When θe decreases with height, the atmosphere is said to be

A

potentially or convectively unstable

18
Q

potentially or convectively unstable mean that

A

if the layer in which θe decreases with height was lifted to saturation, then an unstable lapse rate would result. This situation is often found when potentially colder or drier air is located above warm, moist air.
