[单项选择]Agreeable to your request, I send you my reasons for thinking that our northeast storms in North America begin first, in point of time, in the southwest parts: that is to say, the air in Georgia, the farthest of our colonies to the Southwest, begins to move southewesterly before the air of Carolina, begins to move southwesterly before the air of Carolina, which is the next colony northeastward. The air of Carolina has the same motion before the air of Virginia, which lies still more northeastward, and so on northeasterly through Pennsylvania, New York, New England, &c. , quite to Newfoundland.
These northeast storms are generally very violent, continue sometimes two or three days, and often do considerable damage in the harbors along the coast. They are attended with thick clouds and rain.

A. reduction of the density of the air
B. purification of the air
C. removal of oxygen from the air
