SDS-WAS: Ensemble Prediction of Airborne Dust

Comunicación presentada en: International Workshop on Sand and Dust Storms "Dust Sources and their Impacts in the Middle East", celebrado en Estambul del 23 al 25 de octubre de 2017In this study, a one-month period has been selected to perform a deeper verification of the ensemble prediction system in order to evaluate its consistency and reliability. First, the ordinary deterministic verification of the different 12 models or members, as well as their median, has been carried out. Then, verification has been undertaken from a probabilistic point of view. This is a first step for the correct calibration of the system and the implementation of probabilistic forecast products as DSC and DOD EPSgrams. The study has been performed using the HARMONIE monitor deterministic and the HARP (Hirlam Aladin R-based package) probabilistic verification packages

PAR (Photosynthetically Active Radiation) in marine aquarium recreation

Values of PAR (Photosynthetically Active Radiation) have been obtained with an underwater Spherical Quantum Sensor at two shore stations and two large aquarium tanks from the Cantabrian Maritime Museum (Museo Marítimo del Cantábrico, MMC), to compare light environmental modelling. Photoperiod, sunrise, and sunset have been considered, as well as the vibration effect. PAR values indicate that the microcosmos contained in the tanks are essentially a scale or compressed model of the natural medium, as far was light is concerned, including 10 m of the shore water column in only 3 m. Many opportunities and problems are presented by this compression. Dissolved organic materials (DOM), especially gelbstoff, and concentration are related to this process.Los registros del PAR (photosynthetically active radiation) obtenidos en dos estaciones costeras y en otros tantos acuarios del Museo Marítimo del Cantábrico (MMC) han servido para ajustar el modelo de iluminación de estos últimos. Las variaciones en el fotoperiodo, procesos como el amanecer y el ocaso, así como el centelleo, se han tenido en cuenta. Los valores del PAR y el coeficiente de atenuación muestran que los microcosmos de los tanques son esencialmente un modelo a escala o comprimido del presente en el medio natural, y este hecho plantea problemas a los organismos. La presencia y concentraciones de materia orgánica disuelta (MOD), especialmente gilvinas (gelbstoff), tienen relación con este proceso.Instituto Español de Oceanografí

Predicción de polvo mineral atmosférico

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.En el hemisferio norte, el polvo mineral es la principal fuente de partículas en suspensión en la atmósfera. Presenta importantes interacciones con el tiempo y el clima, puesto que interviene en el balance radiativo, la microfísica de nubes y la química atmosférica. A pesar de las dificultades que aún presentan tanto la predicción como la observación de los eventos de polvo, la mejora progresiva de los modelos, así como la intercomparación y verificación de estos modelos, ha permitido abordar la creación de un sistema de predicción por conjuntos y la generación de productos probabilísticos. En esta comunicación se presentan estos productos probabilísticos y multimodelo desarrollados dentro del marco del Sistema de Evaluación y Avisos de Tormentas de Polvo y Arena (SDS-WAS: sds-was.aemet.es)

Becoming primary caregivers? Unemployed fathers caring alone in Spain

This article analyses how unemployed fathers with employed partners broach childcare and how they conceive of their own identities. It aims primarily to determine whether these fathers actually play the part of primary caregivers. The analysis is based on in-depth interviews with 26 unemployed fathers who spent at least three months caring for their children. The findings show that these fathers engaged intensively in a wide variety of caring tasks. Nonetheless, their role as primary caregivers is called into question on the grounds of attitude. They tended to take for granted that they should set aside time and space for themselves, adding to their partners’ dual workload. Moreover, the overall responsibility for care fell largely on mothers. Subjectively speaking, while one group of fathers resorted to egalitarian precepts to normalise their situation, for many others, the inability to meet the standard expectations of traditional masculinity prompted an identity conflict.2019-2

Invasión de polvo en la península ibérica: del 14 al 16 de marzo de 2022

Los pasados días 14, 15 y 16 de marzo de 2022 la península ibérica sufrió una intrusión de polvo en suspensión sin precedente procedente del Sahara. Las intrusiones de polvo africano suelen provocar registros de la concentración de partículas llamadas PM10 (partículas con diámetros de 10 μm o menos) de hasta 325 μg/m³ en la Península, y de hasta 600 μg/m³ en Canarias (Querol et al. 2019)

Sharp increase of Saharan dust intrusions over the Western Mediterranean and Euro-Atlantic region in winters 2020–2022 and associated atmospheric circulation [Discussion paper]

During the winters of the 2020–2022 period, several intense North African dust intrusions affected Europe. Some of them displayed a duration never recorded before. They were referred to as exceptional by several international operational and research institutions considering that wintertime is the season with minimum dust activity in the Mediterranean and Europe. These anomalous winter events with origin in North Africa largely affected western Mediterranean. The main objective of the present work is to analyse the atmospheric drivers (synoptic and large-scale environments) of wintertime (from January to March) dust events over the region covering North Africa, the Western Mediterranean and the Euro-Atlantic during the period 2003–2022. Overall, our results indicate large interannual variability over the study period. A dust catalogue of dust events identified by aerosols retrievals from satellite and aerosol reanalysis products shows a very irregular record and large differences between winter months. The analyses demonstrate a positive anomaly in dust concentration and maximum altitude during the dust events of 2020–2022 in comparison with those of previous years (2003–2019). Winter dust events over western Mediterranean are associated with enhanced blocking activity over the Euro-Atlantic sector, which favours the obstruction of the westerlies and the occurrence of cut-off lows at subtropical latitudes. However, these high-pressure systems can exhibit a large variety of configurations, including meridional dipole blocking patterns with poleward shifted jets or Mediterranean subtropical ridges with an intensified mid-latitude jet. The former was more frequent during the reference 2003–2019 period, whereas the latter was relatively common during the anomalous 2020–2022 period

Characterization of a resilient seagrass meadow during a decline period

Seagrasses are globally threatened ecosystems with essential ecological roles. An important limitation in seagrass conservation efforts is the poor understanding of resilient meadows. The present work studies a meadow, which maintained a large population of Zostera marina and Zostera noltei, during the decline of seagrasses in the Bay of Santander (from 1984 to 2000). The work examines resilience parameters related to the biological traits (biomass, density, length and width of the leaves) and to the associated benthic assemblages. The maturity of the meadow and the changing environmental conditions induced by the torrential regime of the Miera River, have likely improved the resistance to the periods of stress. The adaptation to these fluctuating conditions is reflected in a high seasonal and spatial variability in the biomass, density, morphological traits and benthic assemblages. These variations are related to the summer peaks in the PAR, the sea surface temperature and the freshwater influence along the discharge of the Miera River. This work provides the first seagrass data in Cantabria. The data are dated in the early 2000s and constitute a baseline study for the Bay of Biscay.Las praderas de fanerógamas marinas son ecosistemas globalmente muy amenazados, con funciones ecológicas esenciales. Una limitación importante para su conservación es el limitado conocimiento sobre el papel de las praderas resilientes. El presente trabajo aborda la caracterización de una pradera resiliente, durante el declive de las poblaciones de Zostera marina y Zostera noltei en la bahía de Santander (período 1984-2001). El trabajo examina parámetros de resiliencia relacionados con los rasgos biológicos (biomasa, densidad, longitud y anchura de las hojas) y con las comunidades bentónicas asociadas. La madurez de la pradera y unas condiciones ambientales muy cambiantes, inducidas por el carácter torrencial del río Miera, han favorecido probablemente su resistencia frente a los períodos de estrés. La adaptación a estas condiciones se refleja en una alta variabilidad estacional y espacial en la biomasa, la densidad, los rasgos morfológicos y las asociaciones bentónicas. Estas fluctuaciones parecen responder a los picos de PAR y temperatura del agua y al gradiente a lo largo de la desembocadura del río Miera. Este trabajo proporciona los primeros datos de fanerógamas marinas en Cantabria. Los datos se recogieron a principios de la década de 2000 y constituyen un estudio de referencia para el Golfo de Vizcaya
