The polar low as seen on infra-red satellite images at 8am this morning, with associated rain bands.
Todayís activity at HQ was centred around the polar low.† The latest satellite images and radar were carefully monitored, as were the soundings when they became available.† It became clear during the day that the polar low was moving slower than the models had predicted and deepening more as it moved over the warm ocean currents near the coast.† It was moving more to the left than forecast, looking like it might make landfall later and slightly further up the coast than had been forecast.
day tomorrow gives everyone a break and a chance to rest after all the activity
of the previous week. †In celebration of
the successful flights, and because there was no need to get up early the next
day, a small party was planned for the evening, with desserts being prepared by
Andreas and Vanda.† Erik arrived just in
time to join the party, bringing photos of the polar low that he had flown over
on his flight from Longyearbyen (Spitsbergen) to mainland
tomorrow at midday is at 73N, 8W, just north of Jan Mayen.† This small feature merges with the large
synoptic-scale cyclone that hits
SAPs for all optimisation times highlight the northern edge of the low pressure
system that is developing and moving towards
The SV SAPs also highlight this low pressure system as sensitive, and have some overlap with the SVs.† The SVs for 12hrs optimisation indicate that the southern and eastern parts of the low pressure system are most sensitive.† For 24hrs optimisation the eastern and northern parts of the low pressure system are more important.† This region is also highlighted by the 36hr SV SAPs, as well as a region over Greenland, where the upper-level flow is coming from.
