    UIDB/04209/2020 UIDP/04209/2020The lengthening of the fire season in Portugal has been understudied, although there is evidence of changes in recent decades. In this brief study, we focused on the annual cycles of fire activity and related meteorological fire danger, thus bypassing the problem of subjective definition of what should mark the beginning and end of the fire season. Based on the daily time series of burned areas and occurrences collected in mainland Portugal by state services from 1980 to 2018, we searched for significant changes in the monthly and daily relative in-year distributions. In particular, an exceedance date method was used to determine day-scale trends in the anticipation/prolongation of fire activity in the year. We found an unequivocal diminishing trend in the proportion of annual burned area that occurs in the summer months (July to September), which was offset by an increase in the fraction from January to June. Apparently, the month of March plays an important role in these changes that should be clarified in future analyses. The daily analysis shows a clear shift of the cumulative curves of burned area to the left, which suggests an in-year anticipation of fire activity. Considering the dates of exceedance of the 15% of annual burned area, the found linear trend implies an anticipation rate of 1.34 days per year. Next, we evaluated seasonal changes in fire weather through the annual cycle of cumulative DSR, computed from daily FWI values. The results show, on average, an earlier increase in DSR when comparing the latter second half of the period (2000-2018) with the first one former (1980-1999). This difference develops from April to the end of September. Interestingly, a closer look shows a first increase in the gap as early as March, which disappears in April before steadily increasing again. Finally, we suggested that up-to-date knowledge of the interannual and interdecadal changes in the seasonality of both wildfires and fire weather is a decisive component, but not the only one, of a comprehensive and complex management of the fire season. A good illustration of this complexity is the fact that the annual definition of the fire season window necessarily affects the annual fire cycle by conditioning the ignition calendar.publishersversionpublishe

    UIDB/04209/2020 UIDP/04209/2020The length of the fire season has not garnered much attention within the broad field of meteorological research on fire regime change. Fire weather research on the Iberian Peninsula is no exception in this case; there is no solid understanding on fire season lengthening in Portugal, although recent decades do suggest ongoing transitions. Based on a complete record of fire occurrence and burned area between 1980 and 2018, we first searched for consistent trends in the monthly distribution of fire activity. To determine day-scale changes, an exceedance date method based on annual cumulative burned area was developed. Results show an early onset of fire activity in a range of 23–50 days and no significant extension into autumn, suggesting that existing projections of the lengthening of the fire season in Portugal over the present century have been already achieved. Fire weather results show a trend in the cumulative Daily Severity Rating (DSR), with the last two decades (2000–2018) displaying an early build-up of meteorological fire danger in late spring and early summer. The detailed spatio-temporal analysis based on the daily Fire Weather Index (FWI) shows that June stands out with the largest increase (year-round) in days per month with an FWI above 38.3, the threshold above which fire conditions make suppression uncertain. This aggravated fire weather is likely sustaining early fire activity, thus contributing to a longer critical fire season.publishersversionpublishe

    Ponencia presentada en: VI Simposio Nacional de Predicción, celebrado en los servicios centrales de AEMET, en Madrid, del 17 al 19 de septiembre de 2018.The need for forecasts at an increasingly higher number of locations and time frequency requires a fully automated forecast system. Due to model biases, statistical post-processing is required to improve the quality of the forecasts in variables such as temperature, humidity and wind speed. The automatic forecasting algorithms developed at IPMA provide forecasts up to 10 days and use ECMWF and AROME data

    Fire danger harmonization based on the fire weather index for transboundary events between Portugal and Spain

    Portugal and Spain have a cross-border cooperation protocol on wildfires response for a buffer strip of 25 km for each side of the border. In spite of the success of this collaboration, there are issues to be improved, since Portuguese and Spanish authorities use different methodologies to assess the daily fire danger. A methodology to harmonize fire danger and its interpretation by the Portuguese and Spanish Civil protection authorities in the transboundary buffer strip area is hereby presented. The fire danger index used is the Canadian Fire Weather Index (FWI), which requires input from meteorological data and gives an indication of fire intensity. The fire danger class is an important decision support tool for preventing and fighting wildfires. Since the meaning of FWI values change from region-to-region according to its specific characteristics, a calibration process was performed based on statistical data of the daily FWI values, the number of fires and burned area between 2005 and 2013. The results of the FWI calibration and harmonization of the data for the five danger classes minimizes the fire danger discrepancies across the border. This methodology has the potential to be reproduced in other areas

    Objective: Given the relevance of new instruments for assessing socio-emotional skills validated for the Portuguese population, the present study aimed to translate and validate the Social-Emotional Expertise (SEE) scale. The factor structure of the SEE, reliability, test-retest reliability and the association with other theoretically relevant variables were analyzed. Methods: Participants completed a set of self-report measures assessing social-emotional skills, emotional intelligence, subjective happiness, and social interaction anxiety. The SEE validation study was conducted on two independent samples (N = 466) aged between 18–64 (27.33 ± 11.52). The SEE factor structure, reliability, and validity were analyzed in Sample 1 (n = 258). Additionally, the plausibility of the hierarchical scale model represented by a global score with two second-order factors was tested in Sample 2 (n = 208). Results: The SEE showed a two-factor structure: (1) Adaptability and (2) Expressiveness factors. Confirmatory factor analysis of the second-order hierarchical model revealed a poor fit to the data. The SEE showed good reliability for the total score and factors and adequate test-retest reliability. As measured by the SEE, social-emotional skills revealed positive correlations with emotional intelligence and subjective happiness and negative an association with social interaction anxiety. No significant gender differences were found, and age and years of education were not significantly associated with socio-emotional skills, as assessed by the SEE. Conclusions: The Social-Emotional Expertise scale proved to be a valid and reliable instrument to assess socio-emotional skills in adults in the Portuguese population, being useful for research and intervention practices in the educational and clinical context.Objetivo: Para fazer face à necessidade de novos instrumentos de avaliação de competências socioemocionais validados para a população portuguesa, o presente estudo teve como objetivo traduzir e validar a escala Social-Emotional Expertise (SEE). Foram analisadas a estrutura fatorial da SEE, fidedignidade, estabilidade temporal e a associação com outras variáveis teoricamente relevantes. Métodos: Duas amostras independentes de participantes (N = 466), entre os 18 e os 64 anos (27,33 ± 11,52) foram utilizadas para validar a SEE. Na Amostra 1 (n = 258) foi analisada a estrutura fatorial da SEE, as propriedades psicométricas e a sua associação com outros construtos. Na Amostra 2 (n = 208) foi testada a plausibilidade do modelo hierárquico da escala representado por uma pontuação global com dois fatores. Os participantes preencheram um protocolo de questionários de autorresposta que avaliaram as competências socioemocionais, a inteligência emocional, a felicidade subjetiva e a ansiedade de interação social. Resultados: A SEE apresentou uma estrutura bifatorial composta pelos fatores Adaptabilidade e Expressividade. A análise fatorial confirmatória do modelo hierárquico de segunda ordem indicou um ajustamento sofrível. A SEE revelou uma boa consistência interna para o total e respetivos fatores e uma adequada fidedignidade teste-reteste. As competências socioemocionais (SEE) revelaram correlações positivas com a inteligência emocional e com a felicidade subjetiva, e associações negativas com a ansiedade de interação social. Não foram encontradas diferenças significativas entre os sexos, e a idade e escolaridade não se mostraram associadas às competências socioemocionais avaliadas pela SEE. Conclusões: A escala Social-Emotional Expertise mostrou ser um instrumento válido e fidedigno para avaliar as competências socioemocionais em adultos na população Portuguesa, sendo de utilidade para a investigação e práticas de intervenção no contexto educativo e clínico

    UIDB/04209/2020 UIDP/04209/2020 GFC/0109/2017Available research has extensively examined the spatiotemporal patterns of fire-weather regime in Portugal, but a comprehensive climatology of extreme wildfires is still under development. This study calls for different strategies and scales of analysis aiming to describe the relationships between medium and low troposphere weather conditions and severe fire behaviour in mainland Portugal, between 1980 and 2018. In particular, critical fire-weather patterns and thresholds that can contribute to operational and forecasting know-how in short and medium time ranges are presented. We updated the general trends in the fire regime with a new, longer daily burned area series and developed a method that identifies Extreme Wildfire Periods (EWP) that form the basis for climate analysis. Synoptic analysis using Circulation Weather Types (CWT) showed that the northeasterly and easterly directional flows are significantly associated with EWP and produce the most severe fire-weather conditions. The four main CWT related to extreme fire are driven from anticyclones over the eastern Atlantic between the Azores and the British Isles. However, severe situations can also be regulated by CWT with marginal presence in both summer and EWP: low systems located to the west and northwest of Iberia carrying air masses from the south quadrant are related to catastrophic events. Regarding the antecedent climate, the results indicate that the coincident meteorological drought, whether weak or intense, is a necessary but not sufficient condition for the development of an EWP. An increasing relevance of water stress for shorter intervals preceding EWP, in the order of days and weeks, is apparent. Following these results, fine dead fuel moisture thresholds related to transitions in fire behaviour in Portuguese landscapes are computed using a promising predictive moisture content model. Finally, the different methods used are summoned for the detailed analysis of an EWP starting under unusual synoptic circulation.publishersversionpublishe
