The oceanic surface mixed layer is where communication takes place between the oceanic reservoir of heat, freshwater, and carbon dioxide, and the overlying atmosphere in which we live. The exchange of...
Description and implementation of a MiXed Layer model (MXL, v1.0) for the dynamics of the atmospheric boundary layer in the Modular Earth Submodel System (MESSy)
Description and implementation MiXed Layer model
2015/3/5
We present a new submodel for the Modular Earth
Submodel System (MESSy): the MiXed Layer (MXL) model
for the diurnal dynamics of the convective boundary layer,
including explicit representations of...
MetUM-GOML1: a near-globally coupled atmosphere–ocean-mixed-layer model
atmosphere–ocean-mixed-layer model a near-globally
2015/3/5
Well-resolved air–sea interactions are simulated in
a new ocean mixed-layer, coupled configuration of the Met
Office Unified Model (MetUM-GOML), comprising the MetUM coupled to the...
Temperature and photoperiod effects on phytoplankton growing under simulated mixed layer light fluctuations
Temperature and photoperiod effects phytoplankton growing simulated mixed layer light fluctuations
2014/4/4
We measured specific growth rates of Stephanodiscus minutulus, Nitzschia acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating and constant light in semi-continuous culture a...
Mixed Layer Mesoscales for OGCMs: Model development and assessment with T/P, WOCE and Drifter data
OGCMs T/P WOCE Drifter data
2011/9/8
In this paper we present a model for mixed layer (ML) mesoscale fluxes of an arbitrary tracer in terms of the resolved fields (mean tracer and mean velocity). The treatment of an arbitrary tracer, rat...
Updraft and downdraft characterization with Doppler lidar: cloud-free versus cumuli-topped mixed layer
Doppler lidar cloud-free versus cumuli-topped mixed layer
2010/8/25
For the first time, a comprehensive, height-resolved Doppler lidar study of updrafts and downdrafts in the mixing layer is presented. The Doppler lidar measurements were performed at Leipzig, Germany,...
The sensitivity of stratocumulus-capped mixed layers to cloud droplet concentration: do LES and mixed-layer models agree?
stratocumulus-capped mixed layers droplet concentration LES and mixed-layer models
2010/8/12
The sensitivity of a stratocumulus-capped mixed layer to a change in cloud droplet concentration is evaluated with a large-eddy simulation (LES) and a mixed layer model (MLM). The strength of the seco...
Vertical distribution and composition of phytoplankton under the influence of an upper mixed layer
upper mixed layer aquatic communities phytoplankton species water column
2010/4/6
The vertical distribution of phytoplankton is of fundamental importance for the dynamics and structure of aquatic communities. Here, using an advection-reaction-diffusion model, we investigate the dis...
We present a numerical study of the generation and evolution of a mixed layer in a stably stratified layer of Boussinesq fluid. We use an external forcing in the equation of motion to model the experi...
Physical and chemical properties of the regional mixed layer of Mexico's Megapolis
Physical and chemical properties regional mixed layer Mexico's Megapolis
2009/8/18
The concentration of gases and aerosol particles have been measured at the mountain site of Altzomoni, 4010 m in altitude, located 60 km southeast of Mexico City, 50 km east of Puebla and 70 km northe...
Examination of evaporative fraction diurnal behaviour using a soil-vegetation model coupled with a mixed-layer model
evaporative fraction soil-vegetation model mixed-layer model
2009/5/26
In many experimental conditions, the evaporative fraction, defined as the ratio between evaporation and available energy, has been found stable during daylight hours. This constancy is investigated ov...
Frictional Currents in the Mixed Layer at the Sea Surface
Frictional Currents Mixed Layer Sea Surface
2009/4/3
The wind-driven flow in the mixed layer between the free surface and the top stable sheet of a thermocline is usually turbulent. The frictional component of such a flow may be separated from a depth-i...
Diurnal Variation of Temperature and Energy Budget for the Oceanic Mixed Layer During BOMEX
Diurnal Variation Energy Budget Temperature Oceanic Mixed Layer
2009/4/3
The regularity and completeness of temperature soundings for a 12-day period during the 1969 Barbados Oceanographic and Meteorological Experiment (BOMEX) has permitted an analysis of the diurnal varia...
Observations of the Deepening of the Wind-Mixed Layer in the Northeast Pacific Ocean
