Wind forecasting using Principal Component Analysis

, 2014
We present a new statistical wind forecasting tool based on Principal Component Analysis (PCA), which is trained on past data to predict the wind speed using an ensemble of dynamically similar past events.

Satellite Oceanography for Ocean Forecasting [PDF]

, 2002
This lecture aims at providing a general introduction to satellite oceanography in the context of ocean forecasting. Satellite oceanography is an essential component in the development of operational oceanography. Major advances in sensor development and scientific analysis have been achieved in the last 20 years.

Implementing Operational Ocean Monitoring and Forecasting Systems

, 2022
This guide provides an overview of the entire value chain of an operational ocean monitoring and forecasting system and presents international standards and best practices for setting up such a service. This publication aims to promote the development of new marine forecasting systems around the globe along with the improvement of the existing ones.

Ocean forecasting

Eos, Transactions American Geophysical Union, 1977
The 10‐ to 20‐year goal of the U.S. Navy physical oceanography program is to acquire the capability of accurately predicting the state of the ocean for marine forecasting, search and rescue operations, and pollution control. This ‘ocean forecasting’ is the oceanic equivalent of today's global atmospheric weather forecasting.

Evolutionary computation for climate and ocean forecasting: “El Niño forecasting” [PDF]

, 2002
Abstract It has been recently postulated that the irregular dynamics of El Nino-Southern Oscillation (ENSO) may embed a low order chaotic process12. If true, some aspects of the ENSO variability are predictable. Here, from observations of the annual average Sea Surface Temperature (SST) of the tropical Pacific Ocean (1949-1981) and using an ...

Climate change and ocean acidification impacts on lower trophic levels and the export of organic carbon to the deep ocean [PDF]

, 2013
Most future projections forecast significant and ongoing climate change during the 21st century, but with the severity of impacts dependent on efforts to restrain or reorganise human activity to limit carbon dioxide (CO2) emissions.

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

Advanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

Prospects for Arctic Summertime Sea Ice Prediction Based on Arctic Seasonal Prediction System (ArcSPS)

Earth and Space Science
To satisfy the needs of the Arctic sea ice seasonal prediction in summer, we developed the Arctic Seasonal Prediction System (ArcSPS). This system integrates an Arctic sea ice–ocean–atmosphere coupled model with an ensemble‐based Kalman Filter data ...

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...
