Contribuição da interação troposfera-estratosfera nas ciclogêneses em superfície sobre a América do Sul

Abstract: C Co on nt tr ri ib bu ui iç çã ão o dda a i in nt te er ra aç çã ão o t tr ro op po os sf fe er ra a--e es st tr ra at to os sf fe er ra a n na as s A interação entre troposfera e estratosfera tem grande influência e é de grande importância nos processos de ciclogênese em superfície. Entretanto, não se conhece exatamente a frequência destas interações e nem como podem influenciar na intensidade de ciclones em geral. Este trabalho tem como objetivo geral estudar como os altos níveis da atmosfera afetam o desen… Show more

“…In the same study, it was observed by using PV inversion that the surface temperature anomaly was important in the initial development stages, while the upper‐level PV anomalies contributed to the maximum intensification of the system at later stages. For cyclones in general, Crespo (2015) developed a methodology to associate surface cyclones over SA with upper‐level PV anomalies at 300 hPa for the period 1998–2003. Cyclones associated with PV anomalies during their lifecycle turned out to be more intense, travel longer distances, and have their genesis especially over the extratropical South Atlantic.…”
