RISEmpirically Evaluating Divergence Rates of Atmospheric Trajectories
Publisher: American Meteorological Society
Abstract: Observed Northern Hemisphere divergence rates of phase-space trajectories initially emanating from neighboring points are estimated, using a simple, seasonal, weakly GCM-dependent linear method applied to Ertel potential ...
Forecasting the North Atlantic Oscillation Using North Pacific Surface Pressure
Publisher: American Meteorological Society
Abstract: A statistical forecasting scheme for the North Atlantic Oscillation (NAO) is presented. The forecasts are based on Pacific Ocean surface pressure. With 21 months lead time, skills are significant and useful but modest. At ...
Mechanisms of Eastern Mediterranean Rainfall Variability
Publisher: American Meteorological Society
Abstract: This paper presents a simple theory for the association between observed eastern Mediterranean (EM) rainfall anomalies and North Atlantic (NA) climate variability. Large-scale NA atmospheric mass rearrangements, primarily ...
Thermodynamics of Eastern Mediterranean Rainfall Variability
Publisher: American Meteorological Society
Abstract: This note focuses on thermodynamic changes caused by Eastern Mediterranean (EM) subsidence anomalies. Subsidence anomalies are shown to modulate EM-wide stability with respect to moist ascent. Additionally, convective ...
Climatological Coastal Jet Collision, Intermediate Water Formation, and the General Circulation of the Red Sea
Publisher: American Meteorological Society
Abstract: The authors present climatologies of a numerical model of the Red Sea, focusing on the dynamics of winter intermediate water formation. Northward flowing boundary currents are identified as the major dynamical elements. ...
Diet, Energy, and Global Warming
Publisher: American Meteorological Society
Abstract: The energy consumption of animal- and plant-based diets and, more broadly, the range of energetic planetary footprints spanned by reasonable dietary choices are compared. It is demonstrated that the greenhouse gas emissions ...
Forecasting Eastern Mediterranean Droughts
Publisher: American Meteorological Society
Abstract: A dynamically motivated statistical forecasting scheme for eastern Mediterranean winter rainfall is presented. The scheme is based on North Atlantic sea level pressure precursors. The resulting forecasts are robust and ...
Troposphere–Planetary Boundary Layer Interactions and the Evolution of Ocean Surface Density: Lessons from Red Sea Corals
Publisher: American Meteorological Society
Abstract: A time series of oxygen isotope (δ18O) measurements of a coral from the northern Red Sea (RS) is presented and used as a direct proxy for water surface density ?s. With a relatively constant subsurface density, the generated ...
Land Use and Reactive Nitrogen Discharge: Effects of Dietary Choices
Publisher: American Meteorological Society
Abstract: Modern agriculture alters natural biological and geophysical processes, with magnitudes proportional to its spatial extent. Cultivation is also the main cause of artificially enhanced reactive nitrogen (Nr) availability ...
