Such sensitivity estimates have considerable uncertainty, as a subsequent assessment of multiple studies (Knutson et al. 2010) projected total increases by 2100 of about 2 - 11 % for tropical cyclone intensity, and roughly 20 % for near -
storm rainfall rates.
Our more recent late 21st century projections of hurricane activity continue to support the notion of increased intensity (~ 4 %) and near -
storm rainfall rates (~ 10 to 15 %) for the Atlantic basin (Knutson et al. 2013) as well as for most other tropical cyclone basins (Knutson et al. 2015).

Gourley says, «I take the
rainfall rates the radar is measuring in the sky, and take it down to the surface and measure what every raindrop is doing on the ground,» whether it meanders through the soil or flows across impervious roads and parking lots and into
storm drains and waterways.
Although the sooty exhaust tended to boost lightning
rates, other data suggest that the
storms didn't produce more
rainfall than those over areas nearby, the researchers say.
Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased
rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying
rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to
storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
States that climate models mostly continue to predict future decreases in global TC numbers, projected increases in the intensities of the strongest
storms and increased
rainfall rates
The U.S. Global Change Research Program found that if emission
rates continue unchanged the U.S. is likely to experience stronger coastal
storm surges and more frequent extreme
rainfall events.
Scientists expect more intense
storms to occur in the Midwest throughout the year, and more precipitation to fall in winter and spring.4 If our carbon emissions continue to rise at current
rates, spring
rainfall in Jefferson City is projected to increase 25 percent or more by the end of this century.9, 10
Reports from the Weather Channel indicated the risk for
rainfall rates in the range of 3 inches an hour in some of the heaviest
storm cells.
Worldwide there will likely be an average increase in the maximum wind speed of tropical cyclones (hurricanes and typhoons) of 2 to 11 %.6 Because of the way extremes respond to changes such as these, Category 4 and 5 hurricanes are expected to nearly double in number by the end of the century.7 The
rate of
rainfall associated with tropical cyclones, an important factor in flooding, is expected to increase approximately 20 % within 100 km of the center of these
storms.8
Over the coming decades, Atlantic hurricanes are likely to increase in strength as sea surface temperatures increase, fueling the intensity of
storms in the Atlantic Ocean, and significantly increasing
rainfall rates over those of present day
storms.
On top of bringing heavy
rainfall and
storm surges, the intensity of these recent tempests goes so far beyond what was previously thought to be the peak range of cyclone power that the researchers argued that they require a new level, a category 6, on a widely used
rating scale for hurricanes and typhoons.
Storm surge and winds will have somewhat subsided by the time it hits Manila but the storm is moving slowly and producing enormous rainfall rates over a large
Storm surge and winds will have somewhat subsided by the time it hits Manila but the
storm is moving slowly and producing enormous rainfall rates over a large
storm is moving slowly and producing enormous
rainfall rates over a large area.
There has already been a 20 % increase in
rainfall rates for the top 1 % of
storms since 1958.
It has been tight - lipped even about the risks for its massive oil refinery facilities in coastal areas subject to
storm surges and flooding and associated with sea - level rise and the projected increased intensity and
rainfall rates of North Atlantic hurricanes.
Knutson and Tuleya (2004) estimated the rough order of magnitude of the sensitivity of hurricanes to climate warming to be about 4 % per deg C SST warming for maximum intensities and about 12 % per deg C for near -
storm (100 km radius)
rainfall rates (see also Knutson and Tuleya (2008) abstract here).
Physically, a warmer atmosphere holds more water vapor that can enhance moisture convergence and
rainfall rates in
storm systems such as hurricanes.
The Global Precipitation Measurement or GPM core satellite flew overhead and found some heavy rain occurring when it measured
rainfall rates within the intensifying
storm.
