Available in PDF, EPUB and Kindle. Book excerpt: African waves are the major synoptic system over North Africa in the summer. Previous studies have reported that African waves could be distinguished into the two different waves (African easterly waves and Burpee waves) on either side of the African easterly jet. Burpee waves (BWs) have been studied by numerous researchers, therefore, they are well known in the literature. In contrast, African easterly waves (AEWs) are not understood very well, due to the lack of data gathered over the desert. Previous studies have reported that vertical structures of the AEW is shallow near the surface on the north side of the jet. However, they do not explain the shallow structure of AEWs. Thus, the first objective of this study was to explore the limited height of AEWs by analyzing NCEP reanalysis data. According to these results, the mid-level high over North Africa plays an important role in limiting the height of AEWs. In addition, vorticity budget and streamfunction budget analysis indicate the vortex stretching term is the major dynamic process for vertical development and limitation of AEWs at the low and mid levels. Previous studies have mentioned the African jet is also weakened by African waves, but they did not explain the real-time interaction between them. Therefore, the second objective of this study was to explore the interaction between the jet and the wave. The results of Fourier analysis indicate the relationship between the perturbation and the jet depends on the relative positions between them. Vorticity budget analysis also indicates that zonal vorticity advection is an important term for perturbation on the south side of the jet to develop rotation to increase the jet. In contrast, the planetary vorticity advection is the key dynamic process enabling AEWs to develop on the north side of the jet, causing it to weaken.

Available in PDF, EPUB and Kindle. Book excerpt: Synoptic and Dynamic Climatology provides the first comprehensive account of the dynamical behaviour and mechanisms of the global climate system and its components, together with a modern survey of synoptic-scale weather systems in the tropics and extratropics, and of the methods and applications of synoptic climate classification. It is unrivalled in the scope and detail of its contents. The work is thoroughly up to date, with extensive bibliographies by chapter. It is illustrated with nearly 300 figures and plates. *Part 1 provides an introduction to the global climate system and the space-time scales of weather and climate processes, followed by a chapter on climate data and their analysis *Part 2 describes and explains the characteristics of the general circulation of the global atmosphere and includes the nature and causes of global teleconnection patterns *Part 3 discusses synoptic weather systems in the extratropics and tropics and satellite-based climatologies of synoptic features. It also describes the applications of synoptic climatology and summarises current climatic research and its directions.

Available in PDF, EPUB and Kindle. Book excerpt: Forests, Water and People in the Humid Tropics is a comprehensive review of the hydrological and physiological functioning of tropical rain forests, the environmental impacts of their disturbance and conversion to other land uses, and optimum strategies for managing them. The book brings together leading specialists in such diverse fields as tropical anthropology and human geography, environmental economics, climatology and meteorology, hydrology, geomorphology, plant and aquatic ecology, forestry and conservation agronomy. The editors have supplemented the individual contributions with invaluable overviews of the main sections and provide key pointers for future research. Specialists will find authenticated detail in chapters written by experts on a whole range of people-water-land use issues, managers and practitioners will learn more about the implications of ongoing and planned forest conversion, while scientists and students will appreciate a unique review of the literature.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the formation and maintenance of an African Easterly Wave (AEW) that developed over Northern Africa in 2000. Specifically, the pre-development period of Hurricane Alberto that initially formed over the Ethiopian Highlands (EH) region is studied in conjunction with this AEW disturbance. Based on EUMETSAT infrared (IR) satellite imagery and ECMWF 0.5o observational model (EOM) analysis data, we identified four convective genesis periods (G-I, G-II, G-III, and G-IV) and three lysis periods (L-I, L-II, and L-III). Based on the EOM analysis of the pre-Alberto system, we found that moisture and vertical velocity played a major role in the generation and maintenance of the convective cycles associated with the pre-Alberto system as it traveled westward across Northern Africa. Initially, orographic effects induce vertical velocity and moisture, and as the Alberto system travels westward these parameters are governed more by environmental factors. The National Center for Atmospheric Research (NCAR) Regional Climate Model Version 3.0 (henceforth RegCM3) was used to run the control case and several sensitivity simulations. We found that the EH is important for focusing and organizing AEW features by producing a consistent stationary wave mode, generating lee side vorticity, and initially providing sufficient vertical moisture flux for convection. PBL effects over the EH cause the initial convection in response to diurnal diabetic heating. As this convection propagates downstream, it merges with the orographically generated MV on the lee of the EH and a MCC results. PBL effects and moisture availability are important for propagating and maintaining AEW disturbances as they travel to the west and supporting sufficient moisture by allowing for surface moisture fluxes to affect these systems and aid in convective development. The AEW is slightly modulated by orography downstream from the EH region. Both the EH region and the PBL effects are essential in th.
