Help on the apparent heat source Q1

Dear Grads users,

I am trying to compute the apparent heat source Q1 using NCEP/NCAR with grads.

Q1 = ds/dt + V.grad(s) + omega*ds/dp

s = cpT + gZ,
V = horizontal wind
grad = gradient
d/dt = time partial derivative
d/dp = pressure partial derivative
T =temperature
omega = vertical velocity

There is a way  to do it in grads?
