Abstract Monthly mean maximum and minimum temperatures for over 50% (10%) of the Northern (Southern) Hemisphere landmass, accounting for 37% of the global landmass, indicate that the rise of the minimum temperature has occurred at a rate three times that of the maximum temperature during the period 1951–90 (0.84°C versus 0.28°C). The decrease of the diurnal temperature range is approximately equal to the increase of mean temperature. The asymmetry is detectable in all seasons and in most of the… 
Maximum and Minimum Temperature Trends for the Globe
Analysis of the global mean surface air temperature has shown that its increase is due, at least in part, to differential changes in daily maximum and minimum temperatures, resulting in a narrowing
Long term changes in diurnal temperature range in Cyprus
Asymmetric diurnal temperature change in the Alpine Region
By now there is general agreement that the annual mean temperature of earth's surface has increased during the last century. Recently, it has become obvious that this warming is quite inhomogeneous
A stable boundary layer perspective on global temperature trends
One of the most significant signals in the thermometer-observed temperature record since 1900 is the decrease in the diurnal temperature range over land, largely due to warming of the minimum
Changes in temperature variability in relation to shifts in mean temperatures in the swiss alpine region this century
A study has been undertaken of minimum and maximum temperature trends this century for a number of climatological observing sites in Switzerland, typical of both the lowlands and the Alpine domain.
Trends in surface air temperature and temperature extremes in the Great Basin during the 20th century from ground‐based observations
We analyzed trends in surface air temperature and temperature extremes in the Great Basin during 1901–2010. We found that annual average daily minimum temperature increased significantly (0.9 ±
Asymmetric changes in maximum and minimum temperature in Beijing
SummaryBased on observational data at Beijing since 1940, trends in daily maximum, mimimum and mean temperatures are studied. It is shown that the linear rate of increase in minimum temperature is
Daily maximum and minimum temperature trends in a climate model
The recent observed global warming trend over land has been characterised by a faster warming at night, leading to a considerable decrease in the diurnal temperature range (DTR). Analysis of
Surface air temperature and its changes over the past 150 years
We review the surface air temperature record of the past 150 years, considering the homogeneity of the basic data and the standard errors of estimation of the average hemispheric and global


Global warming : evidence for asymmetric diurnal temperature change.
Analyses of the year-month mean maximum and minimum surface thermometric record have now been updated and expanded to cover three large countries in the Northern Hemisphere (the contiguous United
Simulated Diurnal Range and Variability of Surface Temperature in a Global Climate Model for Present and Doubled C02 Climates
Abstract The variability of surface temperature simulated by a global climate model with a simple mixed-layer ocean is analyzed. The simulated diurnal and seasonal ranges of temperature are compared
Is recent climate change across the United States related to rising levels of anthropogenic greenhouse gases
Global warming as a result of rising concentrations of anthropogenic greenhouse gases is predicted by current climate models. During the period 1948–1987, the concentration of anthropogenic
Assessment of urbanization effects in time series of surface air temperature over land
RECORDS of hemispheric average temperatures from land regions for the past 100 years provide crucial input to the debate over global warming1–4. Despite careful use of the basic station data in some
Effects of Recent Thermometer Changes in the Cooperative Station Network
During the past five years, the National Weather Service (NWS) has replaced over half of its liquid-in-glass maximum and minimum thermometers in wooden Cotton Region Shelters (CRSs) with
Northern Hemisphere Surface Air Temperature Variations: 1851–1984
Abstract A new compilation of monthly mean surface air temperature for the Northern Hemisphere for 1851–1984 is presented based on land-based meteorological station data and fixed-position weather
Cloud changes in a warmer Europe
Cloud cover records for western Europe have been analysed in the context of the ‘warming world’ analogue model described by Lough et al. (1983). It is found that cloud cover has generally increased
Urban heat islands in China
We used 1954–1983 surface temperature from 42 Chinese urban (average population 1.7*106) and rural (average population 1.5*105) station pairs to study the urban heat island effects. Despite the fact
Potential evaporation and soil moisture in general circulation models
Abstract The parameterization of continental evaporation in many atmospheric general circulation models (GCMS) used for simulation of climate is demonstrably inconsistent with the empirical work upon
