The Sea-Breeze Front Analytical Model
Publisher: American Meteorological Society
Abstract: Analytical solutions to the nonlinear equations of motion are used to describe the sea breeze front. It is found that the front can develop when the atmosphere stratification in the heated layer is neutral or unstable. The ...
An Analytical Model of the Diurnal Oscillation of the Inversion Base Due to the Sea Breeze
Publisher: American Meteorological Society
Abstract: The diurnal oscillation of the height of the inversion due to the sea breeze is studied analytically by use of a linear model. The base of the inversion over the sea moved downward during daytime and upward during nighttime. ...
Downwelling along the Northeastern Coasts of the Eastern Mediterranean
Publisher: American Meteorological Society
Abstract: The most prominent winter storms in the eastern part of the Eastern Mediterranean are known as Cyprus cyclones. The surface wind speed is between 15?30 m s?1, and about five such cyclones occur in a typical winter. The ...
Nonlinear Dynamics and Chaos in the Sea and Land Breeze
Publisher: American Meteorological Society
Abstract: In this work the evolution of the sea and land breeze is studied using a nonlinear model under calm synoptic conditions and diurnal periodic forcing of ground temperature. The breeze is examined as a function of the strength ...
Downwelling-Front Instability and Eddy Formation in the Eastern Mediterranean
Publisher: American Meteorological Society
Abstract: The instability of the downwelling front along the southern coast of Asia Minor is studied with a multimode quasigeostrophic model. Linear analysis shows that the most unstable wave has a length of about 100 km, The ...
Interannual Variability in North Atlantic Weather: Data Analysis and a Quasigeostrophic Model
Publisher: American Meteorological Society
Abstract: his paper addresses the effect of interannual variability in jet stream orientation on weather systems over the North Atlantic basin (NAB). The observational analysis relies on 65 yr of NCEP?NCAR reanalysis (1948?2012). ...
Oscillatory Climate Modes in the Eastern Mediterranean and Their Synchronization with the North Atlantic Oscillation
Publisher: American Meteorological Society
Abstract: Oscillatory climatic modes over the North Atlantic, Ethiopian Plateau, and eastern Mediterranean were examined in instrumental and proxy records from these regions. Aside from the well-known North Atlantic Oscillation (NAO) ...
Nonnormal Frontal Dynamics
Publisher: American Meteorological Society
Abstract: The generalized stability of the secondary atmospheric circulation over strong SST fronts is studied using a hydrostatic, Boussinesq, two-dimensional f-plane model. It is shown that even in a parameter regime in which these ...
Low-Frequency Variability in the Midlatitude Baroclinic Atmosphere Induced by an Oceanic Thermal Front
Publisher: American Meteorological Society
Abstract: This study examines the flow induced by an east?west-oriented oceanic thermal front in a highly idealized baroclinic model. Previous work showed that thermal fronts could produce energetic midlatitude jets in an ...
Optimal Vector Interpolation of Wind Fields
Publisher: American Meteorological Society
Abstract: In this paper a method of optimal interpolation of the vector field is suggested. It is shown that the vector estimator and its associated error are independent of the choice of the coordinate system in which to represent ...
