Development of a homogeneous long monthly precipitation dataset for Spain

Póster presentado en: 10th EMS Annual Meeting - 8th European Conference on Applied Climatology (ECAC) celebrado en Zurich, los días 13-17 de septiembre de 2010The purpose of this study is to extend, revise, improve and update the Spanish monthly/annual centenarian precipitation series in order to achieve more consistent variability and trend analyses. We present the compilation of a dataset integrated by 66 long monthly precipitation series, which covers mainland Spain and the Balearic Island

A monthly precipitation database for Spain (1851–2008): reconstruction, homogeneity and trends

The compilation and reconstruction of a dataset integrated by 66 long monthly precipitation series, covering mainland Spain and the Balearic Islands, is presented. The reconstruction is based on the hypothesis that the cessation of data recording at one observatory is followed by the establishment of a new observatory very close to the closed one. In order to detect and adjust for possible multiple change points or shifts that could exist in the precipitation series, the R-package CLIMATOL V2.0 is used. This method enables to take advantage of the whole historical Spanish precipitation network in the detection and correction of inhomogeneities. The analysis of annual precipitation trends indicate a high temporal variability. Negative trends dominate for the period 1951–2008 but not for all observatories. On the other hand, positive trends can be detected in the northern Spain for 1902–2008

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

Spatial variability of COVID-19 first wave severity and transmission intensity in Spain: the influence of meteorological factors

Within the same country, Spain, with the same cultural aspects and containment policies (without lockdown), why in the initial moment of the COVID-19 first wave, given a significant number of infections, the disease prospered more intensely in some areas than in others? The hypothesis is that the meteorological factors, that is, the utbreak weather conditions are relevant factors which could be used as early indicators of the COVID-19 first wave severity and transmission intensity. This paper presents a model that allows predicting COVID-19 first wave severity and transmission intensity in Spain based on early weather informatio

The use of GIS to evaluate and map extreme maximum and minimum temperatures in Spain

Spanish building legislation has recently changed and now requires an updated and restructured Technical Building Code which is in accordance with European directives. The norm contained in this Code is based on studies of extreme values for climatic elements such as temperature, precipitation and wind. Revised maps of extreme values for climatic elements with a 50-year recurrence interval are required. Here, extreme maximum and minimum temperature maps for Spain are evaluated and mapped by means of geographical information technology. The data are extracted from the historical database held by the Spanish Meteorological Institute. Daily extreme temperatures from 1,181 stations with records going back more than 30 years have been used. The maximum and minimum temperatures are determined as 50-year mean recurrence interval values. To obtain these values, a Gumbel distribution is fitted to the extreme annual values extracted from the database. Spatial interpolation in a regular 5 km×5 km grid of the annual maximum temperature is made by ordinary kriging. Meanwhile, for the annual minimum temperature a residual kriging has been applied due to its strong dependence on altitude

Modos principales de oscilación de la precipitación peninsular

Ponencia presentada en: I Congreso de la Asociación Española de Climatología “La climatología española en los albores del siglo XXI”, celebrado en Barcelona del 1 al 3 de diciembre de 1999.[ES]El análisis de Patrones de Oscilación Principales de series de precipitación mensual acumulada filtrada entre 18 y 96 meses dio como resultados un modo complejo con un período de oscilación de 36 meses y un tiempo de amortiguamiento de 10 meses. Los resultados de este análisis produjeron errores menores que los obtenidos con un modelo de persistencia.[EN]Principal Oscillation Pattern analysis is applied to monthly filtered precipitation retaining all variance between 18 and 96 months. A complex mode with an oscillation period of 36 months and an e-folding time of 10 months is obtained. This analysis yields smaller errors than a persistence model do.La financiación para llevar a cabo este trabajo fue proporcionada por el proyecto CLI97-0341-C03-01
