Question

To quantify the advection of, say temperature, we do so for the individual components of the wind, u (the north-south component, by convention positive to the north) and v (the east-west component, by convention positive to the east) Using the following equation, calculate the strength of the temperature advection in the north-south direction from question 4a (u 10 m s1), if the isotherms are 15000 m apart: . AT ADVyuxAy where AT is the change in temperature over the north-south distance, Ay. C $-1

Explanation / Answer

To find :- Strength of temperature advection ADVy in north south direction over distance.

Given :- distance in isotherms, ?y = 15000m,

?T = change in temperature over ?y.( in oC)

component of wind velocity along north south direction,u = 10m/s

now , ADVY = u x ( ?T / ?y)

or, ADVy = 10 x  ?T / 15000

or, ADVy = 0.0006667* ?T oC s-1
