Figure S7. Daily vertical component
of EP flux (which is proportional to the poleward transport of heat or
upward transport of potential energy by planetary wave) at 100 hPa
averaged over (top) 30°N–90°N and (bottom) 30°S–90°S for JAN
2006 The EP flux unit (kg m-1
s-2) has been
obtained by multiplying a factor of the Brunt Vaisala frequency
divided by the Coriolis parameter and the radius of the earth.
