Answer: the northern and southern parts of the ocean
Explanation: the northern hemisphere and southern hemisphere parts of the ocean are big reasons that El Ni~no when the northern hemisphere part of the ocean warms up it changes the wind direction it mostly forms in the 4 corner states and the slower the oceans warm the longer and stronger it will last.
During winter, the temperature of the water at the bottom of Lake Superior in the Northern United States is 4°C (which stands for Celsius). There is a simple explanation for this; in wintertime, the temperature of Lake Superior often stay above -30°F (which stands for Fahrenheit). Most of the time this lake is covered in ice, rendering a cold temperature but not cold enough for Lake Superior not to experience storms when months like October - December roll around the corner.
The source of energy that drives air pressure patterns is the sun, because it's heating a second grader at the equator then at the poles, it creates a circulation in the atmosphere. Hot moist air rises over the equator and Flows at the high-level towards the poles, where it cools and sinks. The equator is there for a region of low pressure, and the poles are regions of high-pressure. If something is being "taken off your shoulders" your experience less pressure, whereas if someone's trying to stand on your shoulders, you'll feel more pressure.
