Signature of Large Aspect Ratio Roll Vortices in Synthetic Aperture Radar Images of Tropical Cyclones
Large Aspect Ratio Roll Vortices Synthetic Aperture Radar Images Tropical Cyclones
2015/7/16
Synthetic aperture radar images of tropical cyclones have been processed into high-resolution surface wind vector fields. Examination of the surface wind divergence and wind stress curl show that wind...
Simultaneous measurements of nitrate, oxygen, and carbon dioxide on oceanographic moorings: Observing the Redfield ratio in real time
nitrate oxygen carbon dioxide
2014/4/16
Autonomous observations of dissolved nitrate, oxygen, and total inorganic carbon (TCO2
, which is derived
from pCO2
and estimates of alkalinity) from sensors on the M1 and M2 moorings, off Monterey...
Numerical simulation of VIV for an elastic cylinder mounted on the spring supports with low mass-ratio
VIV low mass ratio stream-wise and transverse motion two-degree-of-freedom vortex shedding model CFD
2011/9/13
With the development of the offshore deep water oil industry many researchers are focusing on the vortex-induced vibrations (VIV) of deep risers. In the present work, Reynolds–averaged Navier–Stokes (...
Effects of climate on organic carbon and the ratio of planktonic to benthic primary producers in a subarctic lake during the past 45 years
organic carbon benthic primary producers
2014/4/17
The effects of climatic variables on lake-water total organic carbon (TOC) concentrations and benthic and
pelagic primary producers during the past 45 yr were assessed using the sediment records of t...
Double Diffusion and the Distribution of the Density Ratio in the Mediterranean Waterfront Southeast of the Azores
Mediterranean Water Temperture salinity
2009/1/6
Temperture and salinity (T–S) finestructure on vertical scales of 10 db and larger is examined in a 500 by 500 km grid located southeast of the Azores in the North Atlantic. The convergence of several...
Determining the Strength of the Deep Western Boundary Current Using the Chlorofluoromethane Ratio
chloro fluoro methanes Deep Western Boundary Current
2009/1/4
The dilution of a passive tracer during deep water formation and the subsequent advection/mixing in a deep boundary current is modeled with application to chlorofluoromethanes (CFMs) in the North Atla...
Living in transparent lakes: Low food P:C ratio decreases antioxidant response to ultraviolet radiation in Daphnia
Living in transparent lakes Low food P:C ratio decreases antioxidant response ultraviolet radiation in Daphnia
2014/4/21
We experimentally tested the effect of food quality (phosphorus [P] : carbon [C] ratio) on the response of antioxidant enzymes to ultraviolet radiation (UVR) in Daphnia commutata fed with Chlamydomona...
A Relationship between the Bowen Ratio and Sea–Air Temperature Difference under Unstable Conditions at Sea
Bowen Ratio Sea–Air Temperature Unstable Conditions
2008/10/23
At the air–sea interface, estimates of evaporation or latent heat flux and the Monin–Obukhov stability parameter require the measurements of dewpoint (Tdew) or wet-bulb temperature, which are not rout...
On the Estimation of Overwater Bowen Ratio from Sea–Air Temperature Difference
Overwater Bowen Ratio Sea–Air Temperature Difference
2008/7/11
On the basis of thermodynamic considerations, a relationship between overwater Bowen ratio, B, and sea–air temperature difference, (Tsea − Tair), under unstable conditions has been formulated by...
Double-Diffusive Interleaving in the Presence of Turbulence: The Effect of a Nonconstant Flux Ratio
Double-Diffusive Interleaving Turbulence Nonconstant Flux Ratio
2008/7/3
The influence of turbulent mixing on double-diffusively driven thermohaline interleaving is investigated. The problem is formulated using a turbulence-modified flux ratio to link the fluxes of T and S...
