Abstract Variations and trends in extreme cold airmasses over northern North America (th American Meteorological Society Annual Meeting )
When the continuous CO 2 data are segregated into these two trajectory sectors for the period of observation, air masses originating in the North American sector show a higher CO 2 mixing ratio by 2 ppm in winter and lower by 3 ppm in summer, compared to air masses arriving from the ...
This region is part of the North American Cordillera, which forms a continental hydrologic divide and headwaters for some of the largest rivers in North America. Mountainous terrain complicates precipitation patterns due to the orographic effect, wherein moist air is forced upwards along windward ...

C. NA anthropogenic air masses with only 6% refractory material in the accumulation mode can be clearly distinguished from BF air masses. Overall, during the campaign rather small amounts of black carbon from the North American continent were transported towards Greenland during the summer POLARCAT...
(e.g. air temperature) over the North America. During the El Niño winter months, often the southern part of the United States (US) experiences colder than normal conditions, whereas the northern part of North American are warmer. The situation is just opposite during the La Niña winters...
Tipping is a big deal in North America. Hospitality wages in almost all North American countries are low, so an appropriate tip of between 15-20% of the bill. Having a wad of $1 bills will make your time tipping in North America much easier.Keep...
3.2.2 North American Arctic air mass formation Both dynamics and thermodynamics have roles in the formation of extreme cold-air masses. Wexler (1936, 1937) postulated that the cold air was formed at the surface by radiative cooling from a snow-covered ground under clear, windless conditions, cr...
in Pico Island, Azores, where air masses from the surrounding continents (Africa, Europe, Central and North America) pass through, carrying aerosols with anthropogenic (Sb, Br, Mo, U, Se and Tb) and/or natural emissions (Fe, Co, La, Na, Sm, Cr, Zn, Hf, K and Th); (2) TERCEIRA...
In cases of transport from Central America, air masses are predominantly within the North American model domain, resulting in a lower inbound ozone contribution. Conversely, due to TMF being located toward the western portion of the model domain, the inbound ozone source in GEOS-Chem is larger...
