Climate is the most important factor of plants distribution in global and regional scale. Understanding the current distribution of vegetation cover and its interaction with climate regularity is important for predicting its future. In order to determine the effective climate factors in plant life-form in Polour rangelands in the Damavand summit (2400 to 4100 m above sea level), Iran, a study w...

T his is the fourth in a series of BAMS articles on climate extremes in the United States (U.S.). These papers are based on workshops where leading scientists in the field came together to determine how best to assess the state of the science in understanding long-term climate variability and changes in various types of extreme events affecting the United States. The first workshop focused on s...

Introduction: Safety climate received substantial attention due to its potential for explaining variation in safety-related outcomes. The present study examined degree of safety climate related to fatalism and perceived helplessness among workers’ Isfahan Steel Company. Materials and Methods: The current study was a correlation study. Sample consisting of 189 employees in Isfahan Steel Compan...

This paper evaluates evidence that fish stocks in Africa's inland waters are climate-driven and cannot be stabilized by conventional fisheries management measures. We draw on published material and our own recent and on-going research in Lake Chad and the East African Great Lakes area to propose that fisherfolk's livelihood strategies are well adapted to both seasonal and inter-annual climate-i...

The literature survey reviews our present understanding of the Madden Julian Oscillation. This perturbation to the circulation of the tropical atmosphere involves anomalies in climate elements such as pressure, wind, outgoing long wave radiation, and temperature. It is successfully simulated by the present generation of general climate and atmospheric general circulation models. The literature ...
