- A. Dai, K. Trenberth, Taotao Qian
- Environmental Science
- 1 December 2004
A monthly dataset of Palmer Drought Severity Index (PDSI) from 1870 to 2002 is derived using historical precipitation and temperature data for global land areas on a 2.58 grid. Over Illinois,…
Drought under global warming: a review

Increasing drought under global warming in observations and models
- A. Dai
- Environmental Science
- 2013
Historical records show increased aridity over many land areas since 1950. This study looks at observations and model projections from 1923 to 2010, to test the ability of models to predict future…
The changing character of precipitation
- K. Trenberth, A. Dai, R. Rasmussen, D. Parsons
- Environmental Science
- 1 September 2003
Abstract From a societal, weather, and climate perspective, precipitation intensity, duration, frequency, and phase are as much of concern as total amounts, as these factors determine the disposition…
Precipitation Characteristics in Eighteen Coupled Climate Models
- A. Dai
- Environmental Science
- 15 September 2006
Abstract Monthly and 3-hourly precipitation data from twentieth-century climate simulations by the newest generation of 18 coupled climate system models are analyzed and compared with available…
Characteristics and trends in various forms of the Palmer Drought Severity Index during 1900–2008
- A. Dai
- Environmental Science
- 27 June 2011
[1] The Palmer Drought Severity Index (PDSI) has been widely used to study aridity changes in modern and past climates. Efforts to address its major problems have led to new variants of the PDSI,…
Estimates of Freshwater Discharge from Continents: Latitudinal and Seasonal Variations
- A. Dai, K. Trenberth
- Environmental Science
- 1 December 2002
Annual and monthly mean values of continental freshwater discharge into the oceans are estimated at 18 resolution using several methods. The most accurate estimate is based on streamflow data from…
Recent climatology, variability, and trends in global surface humidity
- A. Dai
- Environmental Science
- 1 August 2006
In situ observations of surface air and dewpoint temperatures and air pressure from over 15 000 weather stations and from ships are used to calculate surface specific (q) and relative (RH) humidity…
Effects of Clouds, Soil Moisture, Precipitation, and Water Vapor on Diurnal Temperature Range
- A. Dai, K. Trenberth, T. Karl
- Environmental Science
- 1 August 1999
The diurnal range of surface air temperature (DTR) has decreased worldwide during the last 4‐5 decades and changes in cloud cover are often cited as one of the likely causes. To determine how clouds…
