1. Water in the ocean: The sun's rays heat the surface of the ocean, causing the water temperature to rise. This warmer water then mixes with cooler water below the surface, creating ocean currents. The temperature of the water can vary greatly depending on the location, time of year, and depth.
2. Air during a thunderstorm: As warm, moist air rises, it cools and condenses into water droplets, forming clouds. The condensation process releases heat, which further warms the surrounding air. This warmer air can then fuel more powerful thunderstorms. As the storm progresses, the temperature of the air can fluctuate rapidly due to the release of heat and the cooling effect of precipitation.
