Streamflow stationarity in a changing world
Whether river flows remain stationary is of great concern to hydrologists, water engineers, and society in general, yet is subject to substantial debate. Here we provide the first comprehensive assessment of the long-term stationarity of annual streamflow for 11 069 catchments globally. Our observation-based evidence shows that the long-term annual streamflow remains stationary in 79% of catchments with minimal human disturbance, indicating that …
A framework to quantify the inter-annual variation in near-surface air temperature due to change in precipitation in snow-free regions
A negative correlation between near-surface air temperature ( T a ) and precipitation ( P ) has long been recognized over many land regions, but a predictive quantitative relationship has not yet been established. In this study, we examine inter-annual variations in T a with P and investigate how the T a - P relationship varies with aridity in regions without snow coverage. The wetness index is used as a measure of aridity (defined as the ratio o…
Simulated changes in aridity from the last glacial maximum to 4xCO 2
Aridity is generally defined as the 'degree to which a climate lacks moisture to sustain life in terrestrial ecosystems'. Several recent studies using the 'aridity index' (the ratio of potential evaporation to precipitation), have concluded that aridity will increase with CO2 because of increasing temperature. However, the 'aridity index' is—counterintuitively—not a direct measure of aridity per se (when defined as above) and there is widespread …
Little change in global drought over the past 60 years
Pan Evaporation Trends and the Terrestrial Water Balance. II. Energy Balance and Interpretation
Declines in pan evaporation have been reported across the USA, former Soviet Union, India, China, Australia, New Zealand and Canada, among other places. The trend is large – approximately an order of magnitude larger than model‐based estimates of top of the atmosphere radiative forcing. The pan evaporation trend also has a different sign (i.e. decline) from commonly held conceptions. These are a remarkably interesting set of observations. In the …
Pan Evaporation Trends and the Terrestrial Water Balance. I. Principles and Observations
Pan evaporation is just that – it is the evaporation rate of water from a small dish located at the ground‐surface. Pan evaporation is a measure of the evaporative demand over terrestrial surfaces. Declines in pan evaporation have now been reported in many regions of the world. The trends vary from one pan to the next, but when averaged over many pans, they are typically in the range of −1 to −4 mm a −2 (mm per annum per annum). In energetic term…
