Tephigrams

Question 1

upthrust

Answer 1

net pressure force exerted on parcel by environment. equal to the weight of surrounding fluid displaced by the parcel.

Question 2

Bouyancy force

Answer 2

upthrust acting on parcel-weight of parcel

Question 3

Tephigram structure

Answer 3

Graph of ln(theta) and p rotated 45 degrees. Area on a tephigram always represents energy.

Question 4

Ideal gas law state variables

Answer 4

P and T

Question 5

Radiosonde measurements

Answer 5

Temperature, pressure, wind-velocity, dew-point temperature

Question 6

Clouds in Tephigram

Answer 6

When dewpoint temperature and temperature are close together there will probably be a cloud.

Question 7

Parcel path in Tephigram

Answer 7

Follows dry adiabat until it reaches the mixing ratio from dew point at surface. It then follows the wet adiabat. This movement has to be forced.

Question 8

Lifting condensation level (LCL)

Answer 8

Point where parcel lifted from surface will condense. Where the dry adiabat reaches the mixing ratio.
