According to the most recent Intergovernmental Panel on Climate Change report, the wind speed and rainfall rates in tropical cyclones are projected to increase during the 21st century, even while the total number of tropical cyclones remains nearly steady, or even decreases.

For example, the extreme drought that gripped Indonesia during summer and fall (leading to an intense wildfire season) was caused by a dearth of rainfall linked to El Niño and higher temperatures linked to climate change, one study in the report found.

The amount of rainfall during the past 24,000 years seems to be linked to the level of exposure of the Sunda Shelf and in particular to the specific topography of the western edge of the region, rather than to changes in deglacial climate boundary conditions alone.

Importantly, the changes in cereal yield projected for the 2020s and 2080s are driven by GHG - induced climate change and likely do not fully capture interannual precipitation variability which can result in large yield reductions during dry periods, as the IPCC (Christensen et al., 2007) states: ``... there is less confidence in the ability of the AOGCMs (atmosphere - ocean general circulation models) to generate interannual variability in the SSTs (sea surface temperatures) of the type known to affect African rainfall, as evidenced by the fact that very few AOGCMs produce droughts comparable in magnitude to the Sahel droughts of the 1970s and 1980s.»

«From 1910 - 1949 (pre-agricultural development, pre-DEV) to 1970 - 2009 (full agricultural development, full - DEV), the central United States experienced large - scale increases in rainfall of up to 35 % and decreases in surface air temperature of up to 1 °C during the boreal summer months of July and August... which conflicts with expectations from climate change projections for the end of the 21st century (i.e., warming and decreasing rainfall)(Melillo et al., 2014).»

As a result of changes in rainfall production, the amount of liquid water in the cloud may be modified, changing the amount of energy available for release as latent heat during freezing (Rosenfeld et al. 2008); these changes may potentially lead to significant alterations in storm vorticity strength (Tinsley et al. 2012).
