TL;DR: In this paper, an analysis of six missions from the 2003 Coupled Boundary Layers Air-Sea Transfer (CBLAST) field program in major hurricanes Fabian and Isabel using a new variational technique was conducted using a near-surface mean drag coefficient CD of 2.4 × 10−3 with a 46% standard deviation and a mean enthalpy coefficient CK of 1.0 × 1...
Abstract: Quantifying air–sea exchanges of enthalpy and momentum is important for understanding and skillfully predicting tropical cyclone intensity, but the magnitude of the corresponding wind speed–dependent bulk exchange coefficients is largely unknown at major hurricane wind speeds greater than 50 m s−1. Since direct turbulent flux measurements in these conditions are extremely difficult, the momentum and enthalpy fluxes were deduced via absolute angular momentum and total energy budgets. An error analysis of the methodology was performed to quantify and mitigate potentially significant uncertainties resulting from unresolved budget terms and observational errors. An analysis of six missions from the 2003 Coupled Boundary Layers Air–Sea Transfer (CBLAST) field program in major hurricanes Fabian and Isabel was conducted using a new variational technique. The analysis indicates a near-surface mean drag coefficient CD of 2.4 × 10−3 with a 46% standard deviation and a mean enthalpy coefficient CK of 1.0 × 1...

TL;DR: The recent trend of declining winter and spring snow cover over Eurasia is causing a land-ocean thermal gradient that is particularly favorable to stronger southwest (summer) monsoon winds, raising the possibility that the current warming trend of the Eurasian landmass is making the Arabian Sea more productive.
Abstract: The recent trend of declining winter and spring snow cover over Eurasia is causing a land-ocean thermal gradient that is particularly favorable to stronger southwest (summer) monsoon winds. Since 1997, sea surface winds have been strengthening over the western Arabian Sea. This escalation in the intensity of summer monsoon winds, accompanied by enhanced upwelling and an increase of more than 350% in average summertime phytoplankton biomass along the coast and over 300% offshore, raises the possibility that the current warming trend of the Eurasian landmass is making the Arabian Sea more productive.

TL;DR: In this paper, the authors highlight the diverse array of scientifically interesting and socially important weather and climate events in the year of tropical convection (YOTC) and use these constructs to advance the characterization, modeling, parameterization, and prediction of multiscale tropical convections, including relevant two-way interactions between tropical and extratropical systems.
Abstract: The representation of tropical convection remains a serious challenge to the skillfulness of our weather and climate prediction systems. To address this challenge, the World Climate Research Programme (WCRP) and The Observing System Research and Predictability Experiment (THORPEX) of the World Weather Research Programme (WWRP) are conducting a joint research activity consisting of a focus period approach along with an integrated research framework tailored to exploit the vast amounts of existing observations, expanding computational resources, and the development of new, high-resolution modeling frameworks. The objective of the Year of Tropical Convection (YOTC) is to use these constructs to advance the characterization, modeling, parameterization, and prediction of multiscale tropical convection, including relevant two-way interactions between tropical and extratropical systems. This article highlights the diverse array of scientifically interesting and socially important weather and climate events assoc...

TL;DR: In this paper, a field study was conducted to determine whether diverse, competing stakeholders in a domain can use collaboration to intentionally initiate innovative public policy affecting that domain, and the results reveal that the stakeholders did collaborate to initiate public policy.
Abstract: A field study was conducted to determine whether diverse, competing stakeholders in a domain can use collaboration to intentionally initiate innovative public policy affecting that domain. The subjects consisted of 61 participants representing 24 stakeholder groups gathered by a U.S. governor that met regularly from 1985 to 1987 to develop a "visionary proposal "for the state's public education. The authors sought to differentiate the substance of collaboration from its result and devised a sociological concept of collaboration with five elements: transmutational purpose, explicit and voluntary membership, organization, interactive process, and temporal property. The results reveal that the stakeholders did collaborate to initiate public policy. The results also show that the collaboration was associated with innovation as hypothesized and that this innovation was incremental rather than radical in nature.

TL;DR: A crude oil tanker scheduling problem faced by a major oil company is presented and solved using an elastic set partitioning model that takes into account all fleet cost components, including the opportunity cost of ship time, port and canal charges, and demurrage and bunker fuel.
Abstract: A crude oil tanker scheduling problem faced by a major oil company is presented and solved using an elastic set partitioning model. The model takes into account all fleet cost components, including the opportunity cost of ship time, port and canal charges, and demurrage and bunker fuel. The model determines optimal speeds for the ships and the best routing of ballast empty legs, as well as which cargos to load on controlled ships and which to spot charter. All feasible schedules are generated, the cost of each is accurately determined and the best set of schedules is selected. For the problems encountered, optimal integer solutions to set partitioning problems with thousands of binary variables have been achieved in less than a minute.
