Mistral data

contact Yonatan Givon at yonatan.givon[at]weizmann.ac.il

A list of dates when mistral wind prevailed in the Gulf of Lion for a climatological period.

The Mistral dates were derived from a coupled requirement of a surface low in the Gulf of Genoa (ERA-INTERIM) and northerly 10-m wind (+-45 degrees, > 2 m/s) in the Gulf of Lion (WRF-ORCHIDEE).

The index is given daily for the period of 1/9/1981-1/9/2016.

The data include also attribution to clusters (column 1), the dates are on column 2, and the estimated Mistral intensity appears in column 3, where intensity 1 corresponds to the relatively weak clusters 1, 3, 4, 6, 8, 9, 11, 12, 13, 16, and intensity 2 corresponds to the more intense clusters, i.e., 2, 5, 7, 10, 14, 15.

Med-CORDEX data

Med-CORDEX is an open club of Mediterranean climate model developers and users, science-driven, self-organised and based on voluntary efforts.

Med-CORDEX develops reference modelling frameworks to provide coordinated regional climate simulations for the study of the various components of the Mediterranean climate system (atmosphere, land, ocean, aerosols).

In its phase 2 (from 2016 onwards), the overarching goals of the Med-CORDEX initiative (rephrased from Ruti et al. 2016) are to:

Understand the past variability of the Mediterranean regional climate system and characterize its possible future evolution.

Investigate, understand and improve the description of regional climate phenomena with emphasis on phenomena of importance for climatic impacts.

Contribute to improve the characterization of the impacts of the Mediterranean climate variability and climate change.

To fullfill these goals, the phase 2 of Med-CORDEX is based on five modelling pillars:

1. • The Baseline runs based on a large ensemble of fully-coupled regional climate system models inherited from Med-CORDEX phase 1.
   • The CORDEX FPS-convection based on convection-permitting regional climate models
   • The CORDEX FPS-aerosol based on an improved representation of aerosols in the regional climate models
   • The CORDEX FPS-airsea based on an improved representation of small-scale oceanic processes and air-sea coupling in the region climate system models
   • The Free Modelling Zone (FMZ) targeting to study the limitations of the current Med-CORDEX modelling protocols and to test new modelling ideas

*FPS: Flagship Pilot Study
