Question

Portland, in southern Maine, was under the influence of the northeastern Low. The wind at Portland, where the pressure was '969,' meaning 996.9 mb, showed the air was moving generally toward the ________ at about 15 knots. The wind shaft is plotted crossing New Hampshire and has one long and one short feather. (It may help to extend the wind arrow through the station circle in the direction the air is flowing and add an arrowhead.)

a) East
b) West
c) North
d) South

Answer 1

In the context of a northeastern Low influencing Portland, Maine, the wind is found to be moving generally toward the southeast at about 15 knots as indicated by the meteorological data. Hence, the correct option is (a).

Step-by-step explanation:

The student's question requires an application of meteorological knowledge, specifically regarding wind patterns and barometric pressure. When a northeastern Low influences a region like Portland, Maine, the wind surrounding a low-pressure system in the Northern Hemisphere circulates counterclockwise and inward.

Given that the wind shaft with one long and one short feather represents a wind speed of approximately 15 knots and is plotted crossing New Hampshire from Portland, we can deduce that the air was moving generally toward the southeast.
