  • In this paper we prove the global existence and uniqueness (regularity) of strong solutions to the three-dimensional viscous primitive equations, which model large scale ocean and atmosphere dynamics. 1. Introduction Large scale dynamics of oceans and atmosphere is governed by the primitive equations which are derived from the Navier-Stokes equations, with rotation, coupled to thermodynamics and salinity diffusion-transport equations, which account for the buoyancy forces and stratification effects under the Boussinesq approximation. ...

  • Humankind’s fascination with Mars predates recorded history. The bright planet with the reddish tint is unique among the other celestial objects. Tycho Brahe’s observations of its unpredictable motion were deciphered by Johannes Kepler in the early 17th century as he developed his laws of planetary motion. Galileo trained his telescope on Mars and saw it as a disk in 1610. Later in the 1600s, Christiaan Huygens and Gian Cassini drew the first maps of the Martian surface.

  • Climate dynamicists generally characterize the Hadley circulation in terms of some derived meteorological parameters, such as the mass stream function (the nondivergent part of the flow) or the velocity potential (the divergent circulation), both of which are based on measurements of the three-dimensional wind field. Yet, we know very little about how such indices have varied in the past—beyond the most recent decades.

  • In Salah – In Salah Gas is a joint venture between BP (33 percent), Sonatrach (35 percent) and Statoil (32 percent). The project comprises a phased development of eight gas fields located in the Ahnet-Timimoun Basin in Algerian Central Sahara. The initial development focuses on the exploitation of the gas reserves in the three northern fields. These gas fields contain CO2 concentrations ranging from one to nine percent, which is above the export gas specification of 0.3 percent and, therefore, requires CO2 removal facilities.

  • The self-organizing map, first described by the Finnish scientist Teuvo Kohonen, can by applied to a wide range of fields. This book is about such applications, i.e. how the original self-organizing map as well as variants and extensions of it can be applied in different fields. In fourteen chapters, a wide range of such applications is discussed. To name a few, these applications include the analysis of financial stability, the fault diagnosis of plants, the creation of well-composed heterogeneous teams and the application of the self-organizing map to the atmospheric sciences...

  • Applicants should identify themselves as unique and stress how their contribution to the business school setting will be distinctive, embracing points of difference as opposed to burying them in ad- missions essays. After all, the very things that make them different could be what scores them a seat in a desirable MBA program. Additionally, applicants should prepare themselves to adapt to changes in the dynamic MBA admissions process.

  • Mangalore coast is a stretch of about 22 Kms at the western part of the Western Ghats of the Indian peninsula. This area is receiving huge quantity of pollution load from the major industries and factories located nearby. This pollution load is discharged into the sea either directly or through the major west flowing rivers of the region, Nethravathi and Gurupura. The pollution load includes runoff of the sediment, waste from oil refineries, nutrients and pesticides, iron ore residues from the nearby iron are company and chemicals from the chemical factory from the point source.

  • On 30 June 1908, in Central Siberia of the U.S.S.R., an extraordinary event occurred (Oliver, 1928 ; Crowther, 1931). Eyewitnesses reported a giant fireball moving across the sky followed by an overpowering shockwave. Trees were radially toppled over thousands of square kilometers, seismic and atmospheric disturbances were recorded as far away as England, and the next several nights were sufficiently bright for reading. However, no significant impact crater was formed nor was any extraterrestrial matter found in the immediate area.

  • This textbook is intended as an introduction to the physics of solar and stellar coronae, emphasizing kinetic plasma processes. It is addressed to observational astronomers, graduate students, and advanced undergraduates without a background in plasma physics. Coronal physics is today a vast field with many different aims and goals. Sorting out the really important aspects of an observed phenomenon and using the physics best suited for the case is a formidable problem.

  • This book gives an account of the modern view of the global circulation of the atmosphere. It brings the observed nature of the circulation together with theories and simple models of the mechanisms which drive it. Early chapters concentrate on the classical view of the global circulation, on the processes which generate atmospheric motions and on the dynamical constraints which modify them. Later chapters develop more recent themes including low frequency variability and the circulation of other planetary atmospheres....
