This preliminary study employs Wolfe's cluster analysis program (NORMIX) in the bivariate normal classification of North American air masses. Once-daily observations of potential temperature and mixing ratio were classified by the NORMIX program into 'types' which represent different air masses. The ...
(1939), An introduction to the study of air mass analysis. By Jerome Namias. Fourth Ed., enlarged and revised, including “Characteristic properties of North American air masses,” by H. C. Willett and “The Norwegian wave-theory ... ...
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...
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 ...
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 the cities and small towns, you’ll uncover the strong connection North Dakota has with its past through restored frontier and Native American villages – all while learning just why Theodore Roosevelt held the state in such high esteem. ...
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...
Sensitivity studies have been performed along idealized trajectories, and it is found that the potential impact of North American emission sources is maximized by transport of air at high altitudes, in drier conditions and in conditions where mixing of the air with background air masses is ...
“Methods” section for details about the measurement or calculation of these parameters. To conserve space, only the 2015–2017 data are presented in their exact geographic locations on a North American ocean margin map, while earlier data are plotted at the correct latitude with a longitude ...
They are crossing North American. 2. Why are they not flying directly to the Atlantic coast? They are not flying directly to the Atlantic Coast because they want to take the train from west to east across Canada./ They want to see Canada./ They want to travel across Canada. 3. What ...
