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...
متن کاملFrom the Tropics to the Poles in Forty Days
Field experiments show that the poleward velocity of high-altitude weather balloons may, on rare occasions, be much higher than the observed poleward winds, while their eastward velocity is much slower than the observed eastward winds. Considering a simple physical model of horizontal particle’s motion in the atmosphere, which includes a realistic model of the pressure field, it is shown that t...
متن کاملLandfills: is wetter better?
Five men with advanced breast cancer were treated with aminoglutethimide (AG) plus replacement dose hydrocortisone. None of the 4 patients with intact testes responded, although 3 did so subsequently to tamoxifen. The previously orchidetomised patient responded to amminoglutethimide for 14 months. Oestrone and oestradiol were suppressed by AG in all patients, but not to the levels achieved by o...
متن کاملLatitudinal trends in shell production cost from the tropics to the poles
The proportion of body mass devoted to skeleton in marine invertebrates decreases along latitudinal gradients from large proportions in the tropics to small proportions in polar regions. A historical hypothesis-that latitudinal differences in shell production costs explain these trends-remains untested. Using field-collected specimens spanning a 79°N to 68°S latitudinal gradient (16,300 km), we...
متن کاملTropical climate at the last glacial maximum inferred from glacier mass-balance modeling.
Model-derived equilibrium line altitudes (ELAs) of former tropical glaciers support arguments, based on other paleoclimate data, for both the magnitude and spatial pattern of terrestrial cooling in the tropics at the last glacial maximum (LGM). Relative to the present, LGM ELAs were maintained by air temperatures that were 3.5 degrees to 6.6 degrees C lower and precipitation that ranged from 63...
