I'm more interested in whether you can find a paper linking day/night temperature differences to frequency of cyclones.
Poorly written.
All separate sentences ducky. Try thinking about it as a whole. The differences between cooler temperatures and warmer temperatures overall.
"Climate change is likely to affect tropical cyclone behaviour in two ways. First, the formation of tropical cyclones most readily occurs when there are very warm conditions at the ocean surface and when the vertical temperature gradient through the atmosphere is strong. As the climate continues to warm, the difference between the temperature near the surface of the Earth and the temperature higher up in the atmosphere, is likely to decrease as the atmosphere continues to warm. As this vertical gradient weakens, it is likely that fewer tropical cyclones will form (DeMaria et al. 2001; IPCC 2012). "

"Second, the increasing temperature of the surface ocean affects the intensity of cyclones (along with changes in upper atmosphere conditions), both in terms of maximum wind speeds and in the intensity of rainfall that occurs in association with the cyclone. This is because the storms draw energy from the surface waters of the ocean, and as more heat (energy) is stored in these upper waters, the cyclones have a larger source of energy on which to draw (Emanuel 2000; Wing et al. 2007). In summary, it is likely that fewer tropical cyclones will form as the climate warms, but a higher fraction of those that do will be intense, more damaging cyclones."
- Not so much.
