The 2nd International AMMA Conference will have four main themes extended by parallel and poster sessions.
West African Monsoon including aerosols, chemistry and ocean
The two-way interactions between the West African Monsoon (WAM) and the rest of the globe are important for determining the variability of the WAM and its global impacts on intraseasonal-to-decadal time-scales. This requires an understanding of the WAM processes, includ-ing mechanisms (e.g. physical, chemical and dynamical) at the regional scale.
Water cycle and surface-atmosphere feedbacks
Understanding the global water cycle and its change due to natural and anthropogenic factors is of critical importance as the availability of water is one of the most limiting parameters for life, agriculture and economic development, especially in the Sahel. A better understanding of the water cycle in the coupled oceanic, atmospheric and continental system will be beneficial for weather and climate forecasting and the management of impacts. It is thus a major issue for AMMA.
A major aim of AMMA is to develop the underpinning science that supports the practical use of climate information in improving health, water resources, food security/agriculture and other key climate-sensitive sectors in West African countries by, for example, helping to identify the relevant climate/environment monitoring, prediction and adaptation strategies. AMMA ensures strong linkages between the work taking place on impacts and that taking place on observed variability and predictability of the WAM.
Forecasting at all scales and its applications
We are hindered in producing skilful predictions in the West African region due to a combination of gaps in our knowledge, gaps in the operational observing system and problems in the way models handle the key scale interactions that characterize the coupled West African monsoon system. These problems are shared by both the “weather prediction community” and the “climate change projection community”. Due to the underlying dynamical processes and to their interaction with vegetation, ocean and chemistry, the WAM region is an ideal area for testing the skill of weather to climate “forecasting” systems, for understanding how much can be achieved through parameterizations or how much we need to consider the use of cloud resolving models for checking tailored forecast products.
The AMMA-Ocean/TACE/PIRATA meeting will be held between 27th and 30th of November, 2007. This meeting will focus on ocean studies particularly discussing the role of the Tropical Atlantic Ocean in the climate system. Four afternoon sessions will address the following topics: (i) Atlantic Intertropical Convergence Zone and Tropical Atlantic Variability (TAV); (ii) Air-sea coupling, sea surface temperature and ocean mixed layer heat budget; (iii) Prediction and predictability of TAV; (iv) Tropical ocean circulation (e.g. oxygen minimum zones, tropical instability waves and equatorial wave dynamics). The morning sessions will be dedicated to special topics like the status and development of the observation system in the tropical Atlantic.
2nd THORPEX Africa Planning meeting up
This meeting will be held just before the conference 23rd and 24th of November 2007 at the University of Karlsruhe. The meeting will focus on finalising the draft THORPEX Plan for Africa and agreeing the priority implementation topics as well as the structure to oversee implementation of the Plan.
Scheduled conference programme up
Plenary sessions will cover the main conference themes given above after a general introduction to AMMA and invited talks on the state of the art of the West African Monsoon.
Parallel and Poster sessions will cover processes (e.g. atmospheric boundary layer, convection and dynamics; oceanic and land-surface processes; chemistry and aerosols processes and interactions with dynamics), integrative science (regional and global modelling: simulations for the 20th & 21st centuries; high impact weather prediction and predictability; reanalysis and data impact studies) as well impacts (prediction of climate impacts, land productivity and water resources; human processes, adaptation and environmental interactions; health).
English and French are the conference languages, simultaneous translation will be provided during plenary sessions.
