Assessing Snow Albedo Feedback in Simulated Climate Change
Publisher: American Meteorological Society
Abstract: In this paper, the two factors controlling Northern Hemisphere springtime snow albedo feedback in transient climate change are isolated and quantified based on scenario runs of 17 climate models used in the Intergovernmental ...
What Controls the Strength of Snow-Albedo Feedback?
Publisher: American Meteorological Society
Abstract: The strength of snow-albedo feedback (SAF) in transient climate change simulations of the Fourth Assessment of the Intergovernmental Panel on Climate Change is generally determined by the surface-albedo decrease associated ...
Does Atmospheric Cooling Drive the Gulf Stream Recirculation?
Publisher: American Meteorological Society
Abstract: A two-layer model for the recirculation is studied Initially, a narrow jet of the upper layer moves eastward with the lower layer remaining stagnant. Att = 0 cold air flows over the narrow front region, all the moving water ...
Matching a Ventilated Thermocline Model with Inertial Western Boundary Currents
Publisher: American Meteorological Society
Abstract: A two-layered ventilated thermocline model is matched with inertial western boundary currents in the southern part of the western boundary region. For general cases the western boundary currents break down much earlier ...
Selecting Project Risk Preventive and Protective Strategies Based on Bow-Tie Analysis
Publisher: American Society of Civil Engineers
Abstract: In the practice of project risk management, project managers need to determine preventive actions to reduce risk probability before the risk occurs and/or protective actions to lower the risk impact after the risk occurrence. ...
Robust Adaptive Backstepping Controller Design for Aircraft Autonomous Short Landing in the Presence of Uncertain Aerodynamics
Publisher: American Society of Civil Engineers
Abstract: To achieve tracking performance and robustness simultaneously during an aircraft’s autonomous short landing phase, a three-dimensional automatic landing system designed using robust adaptive backstepping control is ...
Behavior and Design of Normal- and High-Strength Steel SHS and RHS Columns
Publisher: ASCE
Abstract: The behavior and design of hot-rolled and cold-formed steel square and rectangular hollow section (SHS and RHS) columns, made of both normal- and high-strength material, are addressed in this paper. A series of experiments ...
Periodic Identification of Runoff in Hei River Based on Predictive Extension Method of Eliminating the Boundary Effect of the Wavelet Transform
Publisher: ASCE
Abstract: In order to eliminate the wavelet boundary effect caused by the limitation of data length, a univariate predictive extension method based on phase space reconstruction and least squares support vector machine (LSSVM) is ...
Single-Machine Infinite-Bus Power System Excitation Control Design With Resilient Extended Kalman Filter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To effectively control and maintain the transient stability of power systems, traditionally, the extended Kalman filter (EKF) is used as the real-time state estimator (RTSE) to provide the unmeasurable state information. ...
Theoretical and Experimental Study of Factors Affecting the Suction Force of a Bernoulli Gripper
Publisher: American Society of Civil Engineers
Abstract: A Bernoulli noncontact gripper can generate suction force to achieve noncontact handling by use of axisymmetric radial airflow. An experimental and theoretical study of the factors that affect the suction force and its ...
