Piteraq

The northerly gradient is intensifying in the next few days across the southeast of Greenland as a piteraq wind sets in. On Wednesday the pressure difference in the forecast charts between the Greenland ice cap and the low in the Denmark straits is 61 hPa, that’s over a distance of around 750 km, similar to the distance between Inverness and Exeter as the crow flies. I have often noticed those extremely tight gradients around Cape Farewell at the southern tip of gradient but never realised they might be associated with a piteraq.
