CPTEC recebe visita de pesquisadores da Universidade de Reading, Reino Unido entre os dias 21 a 23 de Janeiro
Entre os dias 21 e 23 de janeiro, o CPTEC receberá a visita de renomados pesquisadores da Universidade de Reading, Reino Unido.

O Dr. Kevin Hodges, desenvolvedor do programa TRACK, que realiza o rastreamento de sistemas meteorológicos a partir de diferentes tipos de dados e já publicou diversos artigos sobre o programa, inclusive com pesquisadores renomados, como o Dr. Hoskins.

O Dr. Kevin co orientou muitos alunos da pós-graduação do INPE, através da utilização do programa TRACK.  

Além do Dr. Kevin, outros dois pesquisadores irão acompanhá-lo nesta visita, a Dr. Liang Guo, que desenvolve informações de umidade dentro do programa de rastreamento e o Dr. Nicholas Klingaman, participante do Projeto DUBSTEP, em conjunto com o CEMADEN e envolve processos e previsibilidade associado à variabilidade sazonal da precipitação no Brasil.

Os visitantes irão ministrar palestras durante a visita, que serão transmitidas ao vivo pelo canal do CPTEC no youtube (https://www.youtube.com/user/cptecinpe):

Dia 22/01 às 9hs no auditório do CPTEC.

 

Title: "The DUBSTEP project: Diagnosing and Understanding Brazilian Subseasonal Tropical and Extratropical Processes"

Dr. Nicholas Klingaman, Principal Research Fellow, National Centre for Atmospheric Science, Reading, UK

 

Abstract: Sub-seasonal floods and droughts in Brazil threaten lives and damage infrastructure and agriculture.  To protect lives and livelihoods, we must understand to what extent such extreme rainfall events can be predicted in existing forecast models, and whether there are situations under which these extremes may be more or less predictable.  The DUBSTEP project -- part of the Newton Fund Climate Science for Services Partnership -- aims to evaluate sub-seasonal prediction skill for Brazilian rainfall, using data from the Sub-seasonal to Seasonal (S2S) database, including prediction skill conditioned on the phase of the Madden-Julian Oscillation and the El Nino Southern Oscillation.  The project also aims to understand the reasons why models lose skill at longer lead times, to inform model development.  This talk will present initial results from the DUBSTEP project and discuss plans for Brazil-UK collaborations to improve sub-seasonal predictions.

Dia 23/01 às 9hs no auditório do CPTEC.

 

Title: "Feature Based Analysis of Atmospheric and Ocean eddies"

Dr. Kevin Hodges e Dr. Liang Guo, National Centre for Atmospheric Science, Reading, UK

 
Abstract:
Feature based analysis of atmospheric and ocean eddies has become a useful analysis tool in providing insights into the distribution, properties and dynamics of such features, how well they are represented in reanalyses, climate models and Numerical Weather Prediction (NWP) and how they may change in the future. Typically methods have been developed that are specific to particular types of feature, however, at least for eddies a general approach can be used. In this talk the general approach used by TRACK will be briefly described and the application to different types of eddies demonstrated in applications for climate and NWP, including extra-tropical and tropical cyclones, mesocyclones and ocean eddies. The feature based analysis can be extended to eddy centered composites to diagnose system structure and how the distribution and properties of eddies varies with different large scale modes of variability, e.g. ENSO, NAO etc.
