Two scientific articles co-authored by IPMA meteorologists were recently published on topics related to Meteorology, Climate and Health:
- "Spatial–Temporal Variability of Hourly Precipitation Extremes in Portugal: Two Case Studies in Major Wine-Growing Regions", Margarida Belo-Pereira, co-author, in collaboration with colleagues from the University of Trás-Os-Montes and Alto Douro (UTAD), Vila Real, Portugal.
Journal of Climatology da Royal Meteorological Society
Brief sumary: Margarida Belo-Pereira (IPMA) é coautora em colaboração com colegas da Universidade de Trás-Os-Montes e Alto Douro (UTAD), Vila Real, Portugal.
This article provides the first climatological study of extreme precipitation events in mainland Portugal, based on hourly observations. Heavy hourly precipitation exhibits large inter- and intra-annual variability, with a pronounced maximum between September and December. In the southern region, these events show a bimodal seasonal distribution, with a secondary peak in April/May. The contribution of precipitation events above 20 mm/h to total daily precipitation is greatest in the autumn in the south and in the summer in the northeast.
A more comprehensive analysis was carried out to examine the dynamic and thermodynamic mechanisms that contributed to two extreme precipitation events caused by thunderstorms in the Douro and Alentejo regions. Different synoptic conditions were behind these events. The Douro event was driven by a cut-off low, whereas the Alentejo event was related to an extratropical cyclone, both in their final stages of development.
- "Meteorological and Environmental Drivers of Cardiovascular Health Risk in an Insular Region (Azores)", Fernanda Carvalho, et. al.
Cardiology and Cardiovascular Research da Science Publishing Group
Brief sumary: Utilizando o modelo estatístico DLNM analisaram-se os impactos que não se manifestam imediatamente mas após um certo período, e os efeitos não lineares das variações deatemperatura do ar nas admissões hospitalares por doenças cardiovasculares na Ilha do Faial, nos Açores. O estudo integra dados meteorológicos e hospitalares de um período de 2010 a 2020 permitindo identificar padrões e realizar previsões relevantes para os sistemas de saúde. O contexto subjacente ao estudo é o do crescente impacto das mudanças climáticas, com eventos extremos de temperatura associados aos riscos à saúde humana.
