Wind changes, and particularly wind changes that are associated with dry cold fronts, have profound effects on fire behaviour and fire-fighting operations (e.g. Cheney et al. 2001). Huang and Mills (2006b) (hereafter Part 1) have reported on the first stage of a larger scale project that aims to improve the understanding and prediction of wind changes in Australia. In Part 1 a method of objecti...

Fatty acid signature analysis (FASA) is a powerful ecological tool that uses essential fatty acids (FA) from the tissues of animals to indicate aspects of diet. However, the presence of vertical stratification in FA distribution throughout blubber complicates the application of FASA to marine mammals. Blubber biopsy samples were collected from adult female southern elephant seals (Mirounga leon...

. introduction global warming and its result, climate change is an important subject investigated especially in the recent decades by researchers throughout the world. in these studies, at first, climatic parameters changes are investigated. considering many uncertainties in the parameters estimation, it is better to choose a method in order to study and analyze the uncertainty band due to diff...

Abstract. Dust events are an important and complex constituent of the atmospheric system that can impact Earth's climate, environment, human health. The frequency dust in Southern High Plains West Texas has increased over past 2 decades, yet their on air quality this region is still unclear. This due to fact there only one monitoring station measures PM2.5 concentrations (particulate matter wit...

The influence of synoptic circulation patterns on surface ozone concentrations at three monitoring sites in southern Sweden was investigated for the spring (April–May) and summer (June–August) periods 1990–2005. Synoptic circulation patterns were classified into six groups based on the Lamb Weather Types (LWTs). The analyses show that the anticyclonic weather pattern (A) and the directional flo...

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...

The derivation of the meridional momentum flux arising from a multiscale horizontal velocity field in the intraseasonal, planetary, equatorial synoptic-scale dynamics (IPESD) multiscale models of the equatorial troposphere is presented. It is shown that, because of the balance dynamics on the synoptic scales, the synoptic-scale component of the meridional momentum flux convergence must always v...

One of the unexplained striking features of tropical convection is the observed statistical self-similarity, in clusters, superclusters, and intraseasonal oscillations through complex multi-scale processes ranging from the mesoscales to the equatorial synoptic scales to the intraseasonal/planetary scales. Here new multi-spatial scale, multi-time scale, simplified asymptotic models are derived s...
