to improve our understanding of the water cycle, with emphases on the predictability and evolution of intense events
by monitoring and modelling: the Mediterranean coupled system (atmosphere-land-ocean), its variability (from the event scale, to the seasonal and interannual scales) and characteristics over one decade (2010-2020) in the context of global change
to evaluate the societal and economical vulnerability to extreme events and the adaptation capacity.
HyMeX objectivesScience topics
The five science Topics
EOP: Enhanced existing observatories and operational observing systems in the target areas of high-impact events:
budgets and process studies(hydrological field experiment)
LOP : Current operational observing system and observatories over the
whole Mediterranean basin: budgets
(data access for research)
SOP: Special observing periods of high-impact events in selected regions of the EOP target areas
(aircraft, R/V, balloons,…): process studies(research atmospheric/ocean field campaigns)
A « Nested » strategy:
Observation strategy
International Science Plan published in 2010, first draft of the Implementation Plan discussed at the 5th HyMeX Workshop in May 2011, new version for end of 2011.
HyMeX data base is set-up and be progressively filled with LOP, EOP, SOP observations and models
Model-observation synergy
LOP/EOP observations
with aims to:
quantify and reduce uncertainties of the future climate projections, advance the modeling of the continental hydrological cycle and the monitoring of
water resources and droughts improve the prediction capabilities of high-impact events by developping
convective-scale ensemble hydrometeorological forecasting systems and mesoscale data assimilation
Process Understanding
Improvement of model parameterizations
SOP/EOP field campaigns
Observations Models
Convection-permitting ensemble hydrometeorological prediction systems
Regional Earth System modelsModel Validation
Mesoscale (incl. land surface) data assimilation Data assimilation in
cloud/precipitation

Preparation of the SOP modelling systems
Preparation of the HyMeX operation center (HOC) co-located with the aircraft base (Montpellier, France), together with virtual operation centers (Spain, Corsica, Italie): webconference, web visualisation platform and forecaster visualisation platform (synergie), involvement of AEMET and Météo-France forecasters for morning briefing, supply of operational and research real-time modelling products
Available deterministic models.
Available ensemble forecasts.
Preparation of dedicated real-time operating mesoscale deterministicmodels over the Mediterranean during the field campaigns: example of AROME-WMED
Incl. Real Time assimilation of EOP-SOP specific observation Datasets (Drifting balloons,…)More European radar data assimilated (work on radar data format for assimilation purposes), non-GTS hourly surface observations,..

Design, implementation and validation of convective-scale EPS is an important objectives of HyMeX
Coupling of these atmospheric ensemble systems with hydrological models to issue hydrological ensemble predictions is an other important objectives
HyMeX SOP1 2012 serves as a testbed for these new EPSLink with TIGGE (report on TIGGE workshops)
Link with DAOS (report on DAOS workshops)
Preparation of the SOP modelling systems
Streamflow simulated by the hydrological model ISBA-TOPMODEL for a flash-flood case over Southern France watersheds
The model is driven by hourly precipitation forecast from an ensemble simulation based on the AROME
model (resolution:2.5 km)
- Global ARPEGE EPS used as LBC combined with ensemble data assimilation - Vié et al (2010)
The model is driven by hourly precipitation fields derived from the AROME NWP operational suite
