[95] [96] However, cold waves are also common, caused by the channeling by the Andes of cold air from the south, making for frequent cold fronts during the winter months and bringing temperatures that can fall below freezing, [97] [98] and occasionally below −10 to −30 °C (14 to −22 °F) at higher altitudes.
In the rare cases when cold fronts move northwards from the south , the cold air masses are not moderated by the surrounding oceans, resulting in very cold temperatures throughout the region. [109] In general, the passage of cold fronts is more common in the south than in the north, and occurs more in winter than in summer. [109]
[4] [5] Due to the maritime influences from the adjoining Atlantic Ocean, [3] its climate is temperate with extreme temperatures (both hot and cold) being rare. [6] Thus, cold air coming directly from the south are moderated by the Atlantic Ocean and warmer than winds from the southwest (which are not moderated by it). [7]
Rainfall patterns are also tied to temperature cycles, with warmer air able to hold more water vapor than cold air. In most Northern Hemisphere regions, the month of February is usually colder than the month of November despite February having significantly later sunsets and more daylight overall.
Central Argentina has hot summers with tornadoes and thunderstorms (in western Argentina producing some of the world's largest hail), and cool winters. The southern regions have warm summers and cold winters with heavy snowfall, especially in mountainous zones. Higher elevations at all latitudes experience cooler conditions.
Arctic, Antarctic, and polar air masses are cold. The qualities of arctic air are developed over ice and snow-covered ground. Arctic air is deeply cold, colder than polar air masses. Arctic air can be shallow in the summer, and rapidly modify as it moves equatorward. [8] Polar air masses develop over higher latitudes over the land or ocean, are ...

This effect is more prominent in the winter months, when the intensity of the cold is more stronger. [9] The Intertropical Convergence Zone reaches the region during the summer months, leading to low pressure, and unstable air masses due to the relatively high land temperatures compared to the sea during this season.
