These storms then draw in air from the polar continental air mass on their advancing cold sectors and from moist tropical gulf air in their warm sectors.
What Mr. Wien is starting to see is investors quietly taking some of their money out of large technology companies and moving it into smaller companies in both hot and cold sectors.
Current cold sectors include energy and semiconductors.
Telecom and health care are among the cold sectors.
Within the cold sector, poleward and west of the cyclone center, small scale or mesoscale bands of heavy snow can occur within a cyclone's comma head pattern.
The area poleward and west of the cold and warm fronts connected to extratropical cyclones is known as the cold sector, while the area equatorward and east of its associated cold and warm fronts is known as the warm sector.
Within the cold sector north to northwest of a cyclone center, in colder cyclones, small scale, or mesoscale, bands of heavy snow can occur within a cyclone's comma head precipitation pattern with a width of 20 mile to 50 mile.
Once a cyclone occludes, a trough 'o'f 'w'arm air aloft, or "trowal" for short, will be caused by strong southerly winds on its eastern periphery rotating aloft around its northeast, and ultimately northwestern, periphery (also known as the warm conveyor belt), forcing a surface trough to continue into the cold sector on a similar curve to the occluded front.
If outflow boundaries move into areas of the atmosphere which are stable in the low levels, such as over colder pockets of ocean or through the cold sector of extratropical cyclones, they can create a phenomenon known as an undular bore, which shows up on satellite and radar imagery as a series of transverse waves in the cloud field oriented perpendicular to the low-level winds.
The indicator selected is defined with respect to gross yearly income of full-time employees in the energy supply sector including special payments, according to the German Federal Statistical Office category 'D Energy supply', which includes electricity, gas, heat and cold supply sector [44].
It is clear that the highest percentage of disappearance is linked to the colder biogeographic sectors of the Mediterranean basin: 11 % in the deep waters of the Strait of Messina (biogeographic sector M), 8 % in the Gulf of Lions and Ligurian Sea (biogeographic sector E), 7 % both in the Northern and Central Adriatic Sea (respectively, biogeographic sectors F and G).
