Climate models suggest that extreme precipitation events will become more common in an anthropogenically warmed climate. However, observational limitations have hindered a direct evaluation of model-projected changes in extreme precipitation. We used satellite observations and model simulations to examine the response of tropical precipitation events to naturally driven changes in surface temperature and atmospheric moisture content. These observations reveal a distinct link between rainfall…

Outstanding research challenges include the influence of mesoscale convective organization, the dependence on the duration considered, and the need to better constrain the sensitivity of tropical precipitation extremes to warming.

Evidence for a weakening of tropical surface wind extremes in response to atmospheric warming

The changes of extreme winds and its links with precipitation are assessed over the past two decades using daily satellite observations and climate model simulations. Both observations and models

Convective Aggregation and the Amplification of Tropical Precipitation Extremes

It is widely believed that precipitation extremes will increase in response to a warming climate, as inferred from both observations and numerical simulations. In the absence of changes in

The physical basis for increases in precipitation extremes in simulations of 21st-century climate change

A physical basis for how precipitation extremes change with climate is given and it is shown that their changes depend on changes in the moist-adiabatic temperature lapse rate, in the upward velocity, and in the temperature when precipitation extremes occur.

EXTREME EVENTS ( A SOBEL AND SJ CAMARGO , SECTION EDITORS ) Precipitation Extremes Under Climate Change

The response of precipitation extremes to climate change is considered using results from theory, modeling, and observations, with a focus on the physical factors that control the response.

Monitoring changes in precipitation and radiative energy using satellite data and climate models

Current changes in the tropical hydrological cycle, including water vapour and precipitation, are presented over the period 1979-2008 based on a diverse suite of observational datasets and

Human contribution to more-intense precipitation extremes

It is shown that human-induced increases in greenhouse gases have contributed to the observed intensification of heavy precipitation events found over approximately two-thirds of data-covered parts of Northern Hemisphere land areas.

Global trends in extreme precipitation: climate models versus observations

Abstract. Precipitation events are expected to become substantially more intense under global warming, but few global comparisons of observations and climate model simulations are available to

Projected increases in intensity and frequency of rainfall extremes through a regional climate modeling approach

Global warming is changing the hydrological cycle in multiple ways such as increased cloudiness, latent heat fluxes, and intense precipitation events. How extreme rainfall events will be influenced

How robust are observed and simulated precipitation responses to tropical ocean warming?

Robust responses and links between the tropical energy and water cycles are investigated using multiple datasets and climate models over the period 1979–2006. Atmospheric moisture and net radiative



Asymmetry of tropical precipitation change under global warming

A clear trend of tropical precipitation changes induced by global warming is found in hemispherical averages of most climate model simulations as well as from observation. It is observed that in

Understanding future patterns of increased precipitation intensity in climate model simulations

In a future climate warmed by increased greenhouse gases, increases of precipitation intensity do not have a uniform spatial distribution. Here we analyze a multi‐model AOGCM data set to examine

Detection of human influence on twentieth-century precipitation trends

It is shown that anthropogenic forcing has had a detectable influence on observed changes in average precipitation within latitudinal bands, and that these changes cannot be explained by internal climate variability or natural forcing.

Intensity of hydrological cycles in warmer climates

Abstract The fact that the surface and tropospheric temperatures increase with increasing CO2 has been well documented by numerical model simulations; however, less agreement is found for the changes

Tropical drying trends in global warming models and observations.

Observed rainfall trends in several data sets show a significant summer drying trend in a main region of intermodel agreement: the Caribbean/Central-American region, which indicates consistent predictions for particular regions.

How Much More Rain Will Global Warming Bring?

Observations suggest that precipitation and total atmospheric water have increased at about the same rate over the past two decades, compared with the climate models and satellite observations.

Dynamic and thermodynamic changes in mean and extreme precipitation under changed climate

Extreme precipitation has been projected to increase more than the mean under future changed climate, but its mechanism is not clear. We have separated the ‘dynamic’ and ‘thermodynamic’ components of

Robust Responses of the Hydrological Cycle to Global Warming

Using the climate change experiments generated for the Fourth Assessment of the Intergovernmental Panel on Climate Change, this study examines some aspects of the changes in the hydrological cycle

Large discrepancy between observed and simulated precipitation trends in the ascending and descending branches of the tropical circulation

Observed and model simulated changes in precipitation are examined using vertical motion at 500 hPa to define ascending and descending branches of the tropical circulation. Vertical motion fields

The Radiative Signature of Upper Tropospheric Moistening

Satellite measurements are used to highlight a distinct radiative signature of upper tropospheric moistening over the period 1982 to 2004 that is accurately captured by climate model simulations and lends further credence to model projections of future global warming.
