Sorry, no etymologies found.
I weeded my library’s copy of that haunting clowns cover for myself, and I will definitely weed this frigid Hawaiian book (must have been taken in subpolar Hawaii) for my own Awful Library Books personal collection.
Most computer simulations of the ocean system in a climate with increasing atmospheric greenhouse-gas concentrations predict a weakening thermohaline circulation in the North Atlantic as the subpolar seas become fresher and warmer1, 2, 3, and it is assumed that this signal will be transferred to the deep ocean by the two overflows.
They plodded aimlessly and despondent through the subpolar surroundings.
North of subpolar low belt, summer heating warms subtropical air masses.
On these modified graphics, we can better visualize the intertropical convergence zone (ITCZ), subtropical high pressure zone, and the subpolar lows.
The development of the subpolar lows in summer only occurs weakly (Figure 5 - over Greenland and Baffin Island, Canada), unlike the Southern Hemisphere.
The meeting of the warm subtropical and cold polar air masses at the subpolar low zone enhances frontal uplift and the formation of intense low pressure systems.
At high latitudes the return flows include export by ice and transport in low-salinity boundary currents, intermediate water (which forms and sinks along the subpolar fronts), and deep water (which sinks on shelves and in gyres).
This collision results in frontal uplift and the creation of the subpolar lows or mid-latitude cyclones.
The spatial pattern shows an increase from minimum values of 50 cm/yr over parts of the North Atlantic subpolar seas.
