Identifying large-scale patterns of unpredictability and response to insolation in atmospheric data
Arizmendi, Fernando; Barreiro, Marcelo; Masoller Alonso, Cristina (Macmillan Publishers, 2017-03-30)
Article
Accés obertUnderstanding the complex dynamics of the atmosphere is of paramount interest due to its impact in the entire climate system and in human society. Here we focus on identifying, from data, the geographical regions which ... -
Impact of lag information on network inference
Rubido, Nicolás; Masoller Alonso, Cristina (Springer, 2018-11-01)
Article
Accés obertExtracting useful information from data is a fundamental challenge across disciplines as diverse as climate, neuroscience, genetics, and ecology. In the era of “big data,” data is ubiquitous, but appropriate methods are ... -
Improving the prediction of the Madden-Julian Oscillation of the ECMWF model by post-processing
Silini, Riccardo; Lerch, Sebastian; Mastrantonas, Nikolaos; Kantz, Holger; Barreiro, Marcelo; Masoller Alonso, Cristina (2022-08-23)
Article
Accés obertThe Madden–Julian Oscillation (MJO) is a major source of predictability on the sub-seasonal (10 to 90 d) timescale. An improved forecast of the MJO may have important socioeconomic impacts due to the influence of MJO on ... -
