Warm air rises. As it rises, it coolsdown and becomes clouds. This makes it difficultfor the air to hold water vapour (水蒸气). When theair gets cold, the water vapour becomes small dropsof water. Sometimes when it is very cold, the watervapour makes ice crystals (冰晶).Some clouds ...

A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
El Nino is the warm phase and happens when trade winds that typically blow across the Pacific toward Asia weaken, allowing warm ocean waters to pile up along the western edge of South America. But during La Nina, the trade winds intensify and cold water from the depths...
At that time, the bright red planet Mars will be shining just to the moon's lower left (or celestial east). This full moon is known as the Wolf Moon, Old Moon, and Moon after Yule. The Indigenous Ojibwe people of the Great Lakes region call it Gichi-manidoo Giizis, the "Great ...
rises, it leaves a lower pressure region below it. This process repeats as air from higher pressure areas moves into the lower pressure area, heats up, and rises, in turn, producing swirls in the air,according to NASA. Once this hot air gets high enough into the atmosphere, it cools ...
begins to rain on this warm or hot surface, the water will evaporate which becomes vapor and rises. This evaporation fog, or steam fog, is named because it resembles steam rising from the surface. This is the exact opposite of the earth’s surface which is cooler than the air temperatures...
The problem with the high pressure is that the already warm or hot air trapped in the dome will become hotter and hotter. Hot air typically rises into the atmosphere, but the dome’s lid causes the air to sink. As the air sinks, it compresses and becomes warmer. That causes the temper...
“Stop it,” I say. “We need to walk.” “But I’mhungry.“ “You ate less than two hours ago. When the sun rises, I’ll make you some more.” “When is it?” she bargains. “Later.” The world is quiet this time of night, just the moon and the rustle of warm breezes ...
Imagine enjoying a soda during a particularly warm day. When you pick up the can, you might notice that it's wet -- there's moisture on the outside. Why is that? As air loses heat, it also begins to lose its ability to retain moisture; the colder surface pulls and collects water ...
