In the Northern Hemisphere, the isotherms are drawn on the map are no...
Explanation:
The isotherms on the map in the Northern Hemisphere are not parallel to the latitudes at several places because of two main reasons: continentality and the presence of warm ocean currents in the temperate and subpolar regions.
Continentality:
The Northern Hemisphere has larger landmasses as compared to the Southern Hemisphere, which leads to the phenomenon of continentality. The continents in the Northern Hemisphere have a greater capacity to absorb and retain heat as compared to the oceans. As a result, during the summer months, the landmasses get heated up more quickly than the adjacent oceans, leading to a temperature gradient. This temperature gradient causes the isotherms to deviate from the latitudes, as the warmer temperatures shift towards the landmasses.
Presence of warm ocean currents:
The Northern Hemisphere has warm ocean currents flowing towards the temperate and subpolar regions. The most notable of these is the Gulf Stream, which flows towards the northwestern coast of Europe. These warm ocean currents help to moderate the temperatures in the surrounding regions, leading to a temperature gradient. This temperature gradient causes the isotherms to deviate from the latitudes, as the warmer temperatures shift towards the currents.
Higher cloudiness:
The subpolar regions in the Northern Hemisphere tend to have higher cloudiness than the corresponding latitudes in the Southern Hemisphere. The clouds act as a blanket, trapping the heat that is radiated from the Earth's surface. This leads to a warming effect, which causes the isotherms to deviate from the latitudes.
Conclusion:
In conclusion, the isotherms in the Northern Hemisphere are not parallel to the latitudes at several places because of continentality, the presence of warm ocean currents, and higher cloudiness. These factors lead to a temperature gradient that causes the isotherms to deviate from the latitudes.
