Carbon sequestration strategies highlight tree plantations without considering their full environmental consequences. We combined field research, synthesis of more than 600 observations, and climate and economic modeling to document substantial losses in stream flow, and increased soil salinization and acidification, with afforestation. Plantations decreased stream flow by 227 millimeters per y...
climatological parameters are among the most important ecological capability evaluation criterias, on other hand, climate changes which has intensified in the past decades and has the consequences such as; increases in climatic threshold phenomena like occurrence of horrific floodings, destructive hurricanes, abnormal and sudden colds and heats, untimely rainfalls and heavy snows, widespread dr...
At Argonne National Laboratory we have developed a high performance regional climate modeling simulation capability based on the NCAR MM5v3.4. The regional climate simulation system at Argonne currently includes a Java-based interface to allow rapid selection and generation of initial and boundary conditions, a high-performance version of MM5v3.4 modified for long climate simulations on our 512...
The vulnerability of human populations and natural systems and their ability to adapt to extreme events and climate change vary with geographic regions and populations. Regional climate models (RCM), composed by an atmospheric component coupled to a land surface scheme and driven over ocean areas by prescribed sea surface temperature, have been developed to produce fine scale regional climate c...
BACKGROUND The adverse respiratory effects of ground-level ozone are well established. Ozone is the air pollutant most consistently projected to increase under future climate change. PURPOSE To project future pediatric asthma emergency department visits associated with ground-level ozone changes, comparing 1990s to 2020s. METHODS This study assessed future numbers of asthma emergency depart...
To evaluate the intervention effects of randomized controlled trials (RCT) involved in theoretical efficacy and actual clinical outcome (effectiveness). Pragmatic-Explanatory Continuum Indicator Summary (PRECIS) is a tool to help researchers make decisions in study design which is consistent with the intended purpose of their trial which can be used in the design of RCT to balance the internal ...
This special issue on \Regional weather models" complements the Oc-tober 1995 special issue on \Climate and weather modeling", which fo-cused on global models. In this introduction we review the similarities and diierences between regional and global atmospheric models. Next, the structure of regional models is described and we consider how the basic algorithms applied in these models innuence ...
