有人验证过这个想法是否正确吗?
这怎么可能是真的?< / p >
空气温度升高会增加水分转移速率，首先是因为在给定的相对湿度，而压力较暖的空气具有较高的绝对湿度，并且携带更多的水分。其次，温暖的空气导致更多的蒸发水和土地。< / p >
There are however a couple of issues that are becoming increasing apparent,
Climate change is (through mechanisms we are yet to fully understand) increasing total rainfall in many areas while decreasing the number of rainfall events they experience. So now when it rains it pours and we see a lot of flooding in areas where the usual pattern was for a lot of lighter rain throughout the year. Between those floods events we see much drier conditions, to the point of drought and forest fires where they had not previously been common.
There has also been an increase in wet season rainfall in a number of fire dependent ecosystems making fuel more abundant during the traditional fire season which is becoming both longer and hotter.
如果为真，这将是一个遥相关受气候变化影响的例子。然而，对极端干旱和极端降水的解释，都是全球变暖的结果，通常被认为有“相反的方向”:更高的温度导致蒸发速度加快，云在最终产生降雨之前储存了更多的水。因此:一方面，某些地方会出现干旱，另一方面，在预计会下雨的地方，会出现大量的水，从而增加降水。也就是说，人们认为全球变暖倾向于加强而不是抑制水循环。< / p >
However, global warming also leads to stronger and more persistent heat waves at certain locations, which means that indeed storms are being "stuck" over other locations for longer times instead of spreading out over larger areas.
Then, in order to answer whether a wildfire and a storm/flood are inter-related by one or (most likely) both of the above consequences of global warming, studying those concrete events and their causes is needed. This is probably already underway for the summer 2021 events.
不，事实上水分率增加。因为更多的热量意味着更多的海洋蒸发。增加湿度。即使是典型干燥的当地气候也会积累更多的水分。全新世时期的非洲有湖泊，面积相当于美国的一个州，撒哈拉是一个有草和湿地的冲积平原。

Nature is involved in the formation of rain. How Mushrooms Make It Rain - YouTube. How Trees Control the Weather. Nature may purposely release particles to form clouds. Water molecules in the atmosphere cannot form a rain droplet without a bigger particle of other type. Human activity may damage the natural system.
There are particles produced by humans in the atmosphere like smoke, dust, microplastics. They may cause water molecules to form rain too early.
Water in the atmosphere is a greenhouse gas. The global mean (average) temperature is rising because of greenhouse gases released by humans. Nature (global ecosystem) may purposely remove water from the atmosphere (by releasing particles) in order to reduce temperature.
Plants grown by humans may not have the correct program in them to release particles on time to support good rain schedule. Plants grown naturally keep local DNA, humans often grow plants from seeds taken from comparatively far away. Also, naturally grown plants may educate each others via signals.
It also means that where such conditions are uncommon rainfall is reduced, because warmer air requires more water vapor to reach saturation and that condition is harder to reach.
The regions mentioned with the question, that are affected by reduced rainfall tend to historically have periods of low rainfall, often related to ocean circulation based phenomena like El Nino Southern Oscillation, Indian Dipole, Atlantic Nino and others that change the distribution of warm and cool surface water, which in turn impacts wind patterns and the amount of water vapor they take up. In combination with warming they can enhance or inhibit evaporation and consequently rainfall.
It does seem likely that global warming is changing those wind patterns as well as their intensity, with consequences for rainfall, in addition to the impacts of the raised capacity to hold water vapor and the raised water vapor threshold for precipitation.
