The city of Manaus, located in the Amazon region, is known for its strong heat and high humidity, presenting an equatorial climate. Throughout the year, the city experiences intense rains and dry periods. On the other hand, in the South of Brazil, in cities like Porto Alegre, the climate is classified as humid subtropical, with hot summers and cold winters, showing a greater thermal variation throughout the year and a more homogeneous distribution of rain over the months. These climatic differences between the North and South of the country are a direct consequence of atmospheric circulation and air masses that influence these regions. Taking into account the concepts of atmospheric circulation, air masses, rains, and winds, how would you explain the difference in the climatic pattern between these two Brazilian cities?

The difference in the climatic pattern between Manaus and Porto Alegre is the result of the influence of proximity to the ocean. As Manaus is further from the ocean, it has a hotter and more humid climate, while Porto Alegre, being closer to the ocean, has a colder and drier climate.

The difference in the climatic pattern between Manaus and Porto Alegre is the result of the influence of latitude. As Manaus is closer to the equator, it has a hotter and more humid climate, while Porto Alegre, being further south, has a colder and drier climate.

The difference in the climatic pattern between Manaus and Porto Alegre is the result of the influence of altitude. As Manaus is at a lower altitude, it has a hotter and more humid climate, while Porto Alegre, being at a higher altitude, has a colder and drier climate.

The difference in the climatic pattern between Manaus and Porto Alegre is the result of the influence of vegetation. The Amazon rainforest in Manaus contributes to a hotter and more humid climate, while the grassland vegetation in Porto Alegre contributes to a colder and drier climate.

The difference in the climatic pattern between Manaus and Porto Alegre is the result of the influence of different air masses and atmospheric circulation patterns. Manaus, in the equatorial region, is influenced by the Intertropical Convergence Zone and the Equatorial Continental air mass, resulting in a hot and humid climate with intense rains. Porto Alegre, in the subtropical region, is influenced by the Tropical Atlantic air mass in summer and the Polar Atlantic air mass in winter, in addition to the mid-latitude atmospheric circulation, resulting in a greater thermal variation and a more homogeneous distribution of rain throughout the year.
