An Improved Numerical Approximation of the Horizontal Gradients in a Terrain-Following Coordinate System
Publisher: American Meteorological Society
Abstract: The use of a fine vertical grid resolution near the surface may lead to a numerically inconsistent approximation of the horizontal gradient terms in a terrain-following coordinate system. This occurs when the distance ...
Mapping Frost-Sensitive Areas with a Three-Dimensional Local-Scale Numerical Model. Part I. Physical and Numerical Aspects
Publisher: American Meteorological Society
Abstract: Radiative frost is one of the most severe weather conditions that affects agricultural activities in many parts of the world. Since various protective methods to reduce frost impact are available, refinements of frost ...
Mapping Frost-Sensitive Areas with a Three-Dimensional Local-Scale Numerical Model. Pad II: Comparison with Observations
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical model was developed to predict the microclimate near the ground surface of local-scale domains during radiative frost events. Its performances are compared with an observational topo-climatological ...
On the Effects of Islands' Geometry and Size on Inducing Sea Breeze Circulation
Publisher: American Meteorological Society
Abstract: Model scaling of the characteristics of the sea breeze circulation involved with circular and slab elongated-symmetric midlatitude islands was performed. Larger horizontal and vertical velocities were indicated over the ...
A Theoretical Study of the Sea and Land Breezes of Circular Islands
Publisher: American Meteorological Society
Abstract: The axisymmetric sea and land breezes of circular islands are studied. First we show, from the equation of turbulent energy, that the marked horizontal convergence of the sea breeze intensifies the turbulence in the flow ...
A Theoretical Study of the Lake and Land Breezes of Circular Lakes
Publisher: American Meteorological Society
Abstract: In this paper the authors study the lake and land breezes of a mesometearological system consisting of a circular lake and a level land area surrounding it. It is assumed that initially the atmosphere is at rest, the ...
Spatial and Temporal Variability in Microclimate and Evaporation over Lake Kinneret: Experimental Evaluation
Publisher: American Meteorological Society
Abstract: Microclimate characteristics and latent and sensible heat fluxes were measured continuously and simultaneously over Lake Kinneret, Israel, during two consecutive summers at the eastern (Ein Gev) and western shores (Sapir) ...
A Theoretical Study of the Land and Sea Breeze Circulation
Publisher: American Meteorological Society
Abstract: Estoque's model for the sea breeze is modified with respect to some essential and other, less essential, details. It is shown among other things that the accelerational terms in the equation for the vertical component of ...
Application of a Numerical Mesoscale Model for the Evaluation of Seasonal Persistent Regional Climatological Patterns
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical mesoscale model has been applied over the irregular terrain of northern Israel in order to simulate the local surface climate pattern associated with typical July stagnate synoptic meteorological ...
