ACTIVITY:   Training on the use of ClimAr portal

2017-11-16. Servicio de Meteorología de la Armada Argentina (SMARA). Buenos Aires, Argentina.

ACTIVITY:   1st South American School of Prediction and Sub-seasonal Forecasting

2017-07-14. Asunción, Paraguay.

The First South American School of Prediction and Sub-seasonal Forecasting was held. The objective was to train the assistants in the predictability sources in this scale and the use of the sub-seasonal forecasts, from their obtaining to the evaluation of their predictive capacity and their levels of uncertainty. The activity was oriented to forecasters of the Meteorological and Hydrological Services of South America and counted on the sponsorship of the World Meteorological Organization among other institutions. Marisol Osman, member of CLIMAR and CLIMAX projects, participated as a coach providing a talk and a workshop on the sources of predictability in South America and trained attendees in the use of the portal .

ACTIVITY:   2nd CLIMAX Argentine Workshop of Interdisciplinary Co-production

2017-06-29. La Leonesa, Chaco. Argentina.

The workshop was oriented to reflect on the climate of the region -main climate variables of relevance, rainfall regime, ENSO-, and the interpretation of climate products: weekly and quarterly scales of forecasts, the concept of probability. The same had the participation and support of the AER-INTA Las Palmas, EFA, Undersecretary of Family Farming, Mercado Campesino, Consortium 9, Municipality of La Leonesa. More Info

ACTIVITY:   New web Portal of experimental products for monitoring and prediction on subseasonal timescales.


The DIVAR Group from CIMA/CONICET-UBA and UMI-IFAECI/CNRS implemented an experimental portal for disseminating the tools under development for monitoring and predicting climate on subseasonal timecales. The portal facilitates that users accessing the information can directly leave their opinions and comments about how to improve them. This initiative is being developed in collaboration with the Argentina National Meteorological Service.

PUBLICATION:   Subseasonal prediction of the heat wave of December 2013 in Southern South America by the POAMA and BCC-CPS models, by M. Osman, and M. Alvarez in Climate Dynamics.


The prediction skill of subseasonal forecast models is evaluated for a strong and long-lasting heat wave occurred in December 2013 over Southern South America. Reforecasts from two models participating in the WCRP/WWRP Subseasonal to Seasonal project, the Bureau of Meteorology POAMA and Beijing Climate Center model BCC-CPS were considered to evaluate their skill in forecasting temperature and circulation anomalies during that event. The POAMA reforecast of 32-member ensemble size, initialized every five days, and BCC-CPS reforecast of 4-member ensemble size for the same date of POAMA plus the previous 4 days were considered. Weekly ensemble-mean forecasts were computed with leadtimes from 2 days up to 24 days every 5 days. Weekly anomalies were calculated for observations from 13th of December to 31st of December 2013. Anomalies for both observations and reforecast were calculated with respect to their own climatology. Results show that the ensemble mean warm anomalies forecasted for week 1 and 2 of the heat wave resulted more similar to the observations for the POAMA model, especially for longer leads. The BCC-CPS performed better for leads shorter than 7 (14) for week 1 (2). For week 3 the BCC-CPS outperformed the POAMA model, particularly at shorter leads, locating more accurately the maxima of the anomalies. In a probabilistic approach, POAMA predicted with a higher chance than BCC-CPS the excess of the upper tercile of temperature anomalies for almost every week and lead time. The forecast of the circulation anomalies over South America could be used to explain the location of the highest temperature anomalies. In summary, for this case, models skill in forecasting surface temperature in a context of a heat wave resulted moderate at lead times longer than the fortnight. However, this study is limited to model-to-model analysis and a multi-model ensemble strategy might increase the skill.

PUBLICATION:   Austral summer precipitation interannual variability and trends over Southeastern South America in CMIP5 models, by L. Díaz and C. Vera in International Journal of Climatology.


The purpose of this study is to assess the ability of Coupled Model Intercomparison Project 5 (CMIP5) models in reproducing the variability and change of the austral summer precipitation observed in Southeastern South America (SESA) along the 20th century and beginning of the 21st. Models show a reduction in mean precipitation biases and inter-model dispersion, and a significant improvement in the representation of the leading pattern of precipitation interannual variability (EOF1), in comparison with Coupled Model Intercomparison Project 3 (CMIP3) models. Changes of the EOF1 activity in the present climate, as represented by both, climate model simulations and rainfall gridded datasets, evidence an increase of the frequency of EOF1 positive events (associated with positive precipitation anomalies in SESA and negative ones in the South Atlantic Convergence Zone) and a decrease of the frequency of EOF1 negative events. Nevertheless there are still large uncertainties due to model differences and the internal variability of the climate system. In order to reduce the impact of model uncertainties, an ensemble of the climate simulations that represent better the features associated with EOF1 activity was built, regardless to which model they correspond. The results obtained with this ensemble confirm that largest precipitation trends in SESA are those represented by climate simulations associated with an increase (decrease) of EOF1 positives (negative) events. It was also found that positive precipitation trends in SESA resulted from climate simulations forced by anthropogenic sources are the largest and significantly different from those from simulations forced by natural sources only, which are not significantly different from zero.
