slide1

Tephigram exercise 1

First we plot the temperature

slide2

Tephigram exercise 1

First we plot the temperature

slide3

Tephigram exercise 1

The red dots are the humidity

slide4

Tephigram exercise 1

Depth of the PBL?

slide5

Tephigram exercise 1

Depth of the PBL

Approx 100 hPa

slide6

Tephigram exercise 1

Q: RH at 1000 hPa?

slide7

Tephigram exercise 1

RH=rv/rs = 5 / 7.7 = 65%

slide8

Depth of the PBL=100hPa. RH@1000hPa=65% @900hPa=85%

Is the PBL well mixed?

Potential temperature at 800 hPa? (two ways)

slide9

Potential temperature at 800 hPa?

291K – Two ways to read…

slide10

700?

Potential temperature at 800 hPa?

291K – Two ways to read…

slide11

What is the condensation temperature and pressure of parcel at 1000 hPa?

910 hPa and 2.5oC

Tephigram exercise 2

slide13

Rainfall evaporated into parcel at 1000 hPa?

Becomes saturated at 7oC, called the “wet-bulb temperature”

Mixing ratio at this point is 6.3 g kg-1

slide14

What is the equivalent potential temperature of parcel at 1000 hPa?

22.5oC – this is the same as the equivalent temperature.

slide15

What is the equivalent potential temperature of parcel at 900 hPa?

900 hPa = 23oC, 700hPa off the page, different tephigram bounds required

It is increasing with height.

slide16

What are the LCL and LFC for parcel at 1000 hPa?

Tephigram exercise 3

LCL is 910 hPa (same as condensation pressure). LFC undefined.

Trigger temperature 17oC, convection unlikely, as requires strong heating.
