Answer:
Eastern Coast of the US, Western coast of Europe and upwards to the polar region
Explanation:
The two images explain clearly that the currents help contribute to warm water, and shown in the second infographic, it says that it brings that water towards the areas listed above. Even without that second picture, we can conclude that it at least goes around north Eastern coast of the US and West Europe as seen by the Gulf Stream current's projection based on arrows.
The greenhouse affect is the reason for the increase in average temperature and the green house affect is contributing to global warming
The air masses that have the greatest influence on weather conditions in the Midwestern United States are continental polar.
This air masses come from the north, they are heavy, low, cold and predominantly dry air masses, and are most intense in the colder part of the year. But they are not the only one, even though they are the dominant ones, the tropical warm and wet climate also has a big influence, especially in the warmer part of the year, and it's influence is gradually increasing.
