Cyclones causing wind storms in the Mediterranean: characteristics, trends and links to large-scale patterns
Cyclones causing wind storms characteristics trends links to large-scale patterns
2010/10/21
A climatology of cyclones with a focus on their relation to wind storm tracks in the Mediterranean region (MR) is presented. Trends in the frequency of cyclones and wind storms, as well as variations ...
An Experimental Study on Wind Loads Acting on a Trimaran PCC
PCC trimaran wind pressure characteristics estimation method
2011/9/9
In recent years, demands for car transportation by a ship have been increasing with favorable economic conditions in auto sector, and the need of a pure car carrier (PCC) has grown quickly. A PCC need...
Uncertainties in wind speed dependent CO2 transfer velocities due to airflow distortion at anemometer sites on ships
wind speed dependent CO2 velocities airflow distortion anemometer sites ships
2010/8/13
Data from platforms, research vessels and merchant ships are used to estimate ocean CO2 uptake via parameterisations of the gas transfer velocity (k) and measurements of the difference between the par...
The interaction of northern wind flow with the complex topography of Crete Island – Part 2: Numerical study
The interaction northern wind flow the complex topography Crete Island
2010/10/20
During the summer months, when northerly winds are blowing over the Aegean Sea the island of Crete modifies significantly the regional airflow as well as the pressure and temperature fields due to its...
Sensitivity of ensemble Lagrangian reconstructions to assimilated wind time step resolution
ensemble Lagrangian reconstructions wind time step resolution
2010/8/12
We study the impact of temporal and spatial resolution and changes in modelled meteorological winds in the context of diffusive ensemble Lagrangian reconstructions. In situ tracer measurements are mod...

Mediterranean offshore extreme wind analysis from the 44-year HIPOCAS database: different approaches towards the estimation of return periods and levels of extreme values
wind extreme values
2010/1/27
The present contribution addresses the performance of a statistical extreme wind analysis over the whole Mediterranean Basin. Estimations of return periods and levels are obtained over offshore areas ...
The relationship between heavy rain (HR) and/or strong wind (SW) events and cyclones is investigated for the Balearic Islands. First, a list of HR and SW events is cross-referenced with an objective c...
Electrical generation by wind turbines is increasing rapidly, and has been projected to satisfy 15% of world electric demand by 2030. The extensive installation of wind farms would alter surface rough...
Technical Note: Sensitivity of 1-D smoke plume rise models to the inclusion of environmental wind drag
1-D smoke plume rise models environmental wind drag Sensitivity
2010/2/1
Vegetation fires emit hot gases and particles which are rapidly transported upward by the positive buoyancy generated by the combustion process. In general, the final vertical height that the smoke pl...
