Amplification of wet and dry month occurrence over tropical land regions in response to global warming

Global land moisture trends: drier in dry and wetter in wet over land

The "dry gets drier, wet gets wetter" (DGDWGW) paradigm is widely accepted in global moisture change. However, Greve et al. have declared that this paradigm has been overestimated. This controversy leaves a large gap in the understanding of the evolution of water-related processes. Here, we examine the global moisture trends using satellite soil moisture for the past 35 years (1979-2013). Our r...

Response of tropical cyclone potential intensity over the north Indian Ocean to global warming

[1] The responses of tropical cyclone (TC) potential intensity (PI) and the associated environmental control parameters over the North Indian Ocean (NIO) to the doubled CO2 concentration are assessed based on the ensemble simulation from 15 coupled general circulation models (CGCMs) participated in the Intergovernmental Panel for Climate Change (IPCC) Forth Assessment Report (AR4). The results ...

Influences of Biomass Burning on Land-atmosphere Interactions and Dry-to-wet Transition over Amazonia

The Response of Precipitation Minus Evapotranspiration to Climate Warming: Why the “Wet-Get-Wetter, Dry-Get- Drier” Scaling Does Not Hold over Land

Simulations with climate models show a land–ocean contrast in the response of P2 E (precipitation minus evaporation or evapotranspiration) to global warming, with larger changes over ocean than over land. The changes over ocean broadly follow a simple thermodynamic scaling of the atmospheric moisture convergence: the so-called ‘‘wet-get-wetter, dry-get-drier’’ mechanism. Over land, however, the...

Corn production and plant characteristics response to N fertilization management in dry-land conventional tillage system

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...
