Cloud classification in NOAA AVHRR imageries using spectral and textural featuers

Clouds contribute significantly to the formation of many of the natural hazards. Hence cloud mapping and its classification becomes a major component of the various physical models which are used for forecasting natural hazards. The problem of cloud data classification form NOAA AVHRR (advance very high resolution radiometer) satellite imagery …

Chief feature of physiographic rainfall variations across India (1813-2006)

While occurrences of water bodies (rivers and canals;reservoirs, tanks and ponds; beels, oxbow lakes and derelict water; and brackish water) across the country depend upon physiographic settings and rainfall conditions, the recharging of the water bodies depends mostly on rainfall which is a highly variable parameter. In this study fluctuation …

Conservation strategies to mitigate impacts from climate change in Amazonia

Protected area systems and conservation corridors can help mitigate the impacts of climate change on Amazonian biodiversity. We propose conservation design criteria that will help species survive in situ or adjust range distributions in response to increased drought. The first priority is to protect the western Amazon, identified as the

Observed change of the standardized precipitation index, its potential cause and implications to future climate change in Amazon

Observations show that the standard precipitation index (SPI ) over the southern Amazon region decreased in the period of 1970

Water recycling by Amazonian vegetation: coupled versus uncoupled vegetationclimate interactions

To demonstrate the relationship between Amazonian vegetation and surface water dynamics, specifically, the recycling of water via evapotranspiration (ET), we compare two general circulation model experiments; one that couples the IS92a scenario of future CO2 emissions to a land-surface scheme with dynamic vegetation (coupled) and the other to fixed vegetation …

The fate of assimilated carbon during drought: impacts on respiration in Amazon rainforests

Interannual variations in CO2 exchange across Amazonia, as deduced from atmospheric inversions, correlate with El Nino occurrence. They are thought to result from changes in net ecosystemexchange and fire incidence that are both related to drought intensity. Alterations to net ecosystemproduction (NEP) are caused by changes in gross primary production …

Drought effects on litterfall, wood production and belowground carbon cycling in an Amazon forest

The Amazon Basin experiences severe droughts that may become more common in the future. Little is known of the effects of such droughts on Amazon forest productivity and carbon allocation. We tested the prediction that severe drought decreases litterfall and wood production but potentially has multiple cancelling effects on belowground …
