prevent overexpansion of the primary flow . This was , of course , evident in the ...

This static - pressure performance map is quite similar to the familiar convergent -
divergent nozzle pressure plots ( e.g. , refs . 3 and 4 ) . As explained in detail in
reference 3 , any change in thrust of a convergent - divergent nozzle when the ...

Method of Analysis To study the planetary - scale divergent circulations , the wind
fields were decomposed into rotational and irrotational components . This was
done by calculating the vorticity and divergence of the wind fields and solving the
