Evolution and future of climate services
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.Climate services are the provision of climate information for use in decision-making taking into account the
context and values of those involved. As climate information is only one, possibly relatively minor, element of what
is needed by those climate-sensitive decision makers, climate services need to be integrated with other information
or services of relevance to the decision-makers. This creates much of the context to be taken into account in the
co-production approaches typically used in climate services to create value. This presentation will describe the
recent evolution, landscape, and market of climate services, the actors in the landscape, what climate services are
being used for, and highlight some of the successes and gaps. The presentation will be based on experiences from
research projects and service contracts
Analysis and effects of the September 2023 DANA episode on the central peninsula
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.The DANA that affected the Iberian Peninsula at the beginning of September 2023 affected large areas of the
peninsula. Especially important were the precipitations in the mouth of the Ebro, Cadiz area and peninsular
center. This type of high intensity phenomena is characteristic of Mediterranean areas in autumn and can also
affect other coastal areas. However, it is not so usual, for the central area of the peninsula, to be affected by this
type of phenomenon with so much impact. In this article we will try to explain a little better the meteorological
situation and the effects that occurred in the most affected inland areas
TRAM: the new numerical model of Meteo-UIB suited for all kinds of regional atmospheric predictions
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.A new limited-area numerical model, TRAM (Triangle-based Regional Atmospheric Model), has recently been
developed at Meteo-UIB. The model utilizes a nonhydrostatic and fully compressible (NHFC) version of the
Navier-Stokes equations and incorporates numerous original characteristics. In this work, it is presented and
validated through numerous 2D and 3D tests. TRAM performs as well as state-of-the-art models and is suitable
for simulating circulations ranging from small-scale thermal bubbles to synoptic-scale baroclinic cyclones,
including orographic circulations, thermally driven flows, squall lines, supercells, all kinds of precipitation
systems, and medicanes. Besides opening a myriad of academic and research applications, TRAM regional
forecasts at different resolutions are available at https://meteo.uib.es/tra
Complementary of offshore energy resources on the Spanish coasts: wind, wave and photovoltaic energy
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.The complementarity of solar, wind, and wave energy resources in hybrid offshore platforms can boost
productivity and lessen energy output variability compared to reliance on a single source. Using ERA5 reanalysis,
this study assesses wind, solar, and wave energy potentials in potential Spanish offshore locations. Wind energy
emerges as the primary resource across Spanish offshore regions, followed by photovoltaic energy. Despite
"drought periods" where no energy is generated, wave energy offers consistent energy flow, particularly in the
northwestern Iberian Peninsula and the Canary Islands. Evaluating the synergy of these energy sources reveals
hybrid platforms' potential to enhance production and reduce variability. While wind and solar energy dominate
production, wave and solar photovoltaic energy are crucial for minimizing variability. This study lays the
groundwork for integrating multiple energy converters on hybrid platforms to advance powerful and sustainable
energy production
Climatic assessment of the wind+solar potential in a insulated system (the Canary Islands)
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.The integration in the energy mix of variable renewable energies (VRE) is neccessary to achieve net-zero
emissions, but is highly compromised due to the intermittency of the electricity generation from these sources. To
help on that, the CLIMAX tool provides guidance about actionable strategies for the deployment of the facilities
that exploit the spatio-temporal complementarity of the two main VRE, wind and solar, in order to reduce the
volatility of their combined production. In this case study, we applied CLIMAX over the Canary Islands and
evaluate the role of the urban areas in promoting the stability of the Canary energy mix while enlarging the
penetration of these two main VRE. Results showed that the optimal scenarios generated with CLIMAX would
reduce the undesired fluctuations of the joint wind+solar electricity production around 30% as compared to a
baseline deployment scenario, and encourage energy policies aimed at maximizing the rooftop area for utility
photovoltaic development
Meteorology and urban air quality: advances in microscale simulations
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.This work presents an overview of microscale modelling studies in urban environments carried out by the Atmospheric Modelling Unit (UNIMA) from CIEMAT during recent years, which illustrates, on the one hand, the evolution of CFD modelling applied to atmospheric flows and, on the other hand, the connection that exists between meteorological variables at the microscale, such as wind speed and direction, turbulence or solar irradiance and urban air quality
Phenological characterization and trends analysis of the Tudela de Duero site (Valladolid)
No full textResumen de la ponencia presentada en: XXXVI Jornadas Científicas de la AME y el XXII Encuentro Hispano Luso de Meteorología celebrado en Cádiz y San Fernando del 13 al 15 de marzo de 2024.Phenology, as a science positioned between ecology and climatology, is an important tool for studies applied to
the agricultural and environmental sectors. Phenological data can characterize the climate (including
microclimates) of a territory, its variability and trends, atmospheric and soil-climatic environmental gradients, as
well as the population genetic variability of biological species in relation to their geographic distribution area.
Phenological data from Tudela de Duero station has been used to perform a simple descriptive statistics analysis
to ecoclimatically characterize the station, define a typical phenological spring ("nature’s calendar"), and search
for trends in the occurrence dates of events. This work presents a summary of the results of these studies
Astronomía y meteorología, consideraciones laborales y profesionales (parte I, astronomía)
Get PDFEl ejercicio profesional de la astronomía y de la Meteorología en España puede desarrollarse tanto en el ámbito privado como en el público, aunque en ambas existe una fuerte presencia de asociaciones de aficionados que colaboran y mantienen unos vínculos muy cercanos con las instituciones/organismos oficiales y el personal profesional. En el ámbito privado puede desarrollarse ambas materias en empresas relacionadas con el sector en cuestión, y sobre todo en grupos audiovisuales o medios de comunicación que necesitan periodistas especializados y divulgadores científicos, y también en otros tipos de plataformas que pueden encontrarse en internet. Igualmente hay empresas vinculadas directa o indirectamente con la Astronomía y/o la Meteorología que pueden contar con asesores o consultores cualificados, con formación en dichas materias, entre su personal. En cualquiera de esos ámbitos privados, la relación laboral será la pactada por la empresa y las personas que van a trabajar en ellas sujetos al Estatuto de los Trabajadores y convenios colectivos de cada sector en concreto, en caso de haberlos, firmando un contrato de trabajo en alguna de las modalidades legalmente contempladas. También podría darse una relación entre la empresa y trabajadores freelance o autónomos. Por otra parte, en el sector público se puede desarrollar una carrera profesional, tanto en astronomía como en meteorología, como funcionario de carrera de la Administración General del Estado en los diferentes cuerpos creados a tal fin, o como personal laboral contratado en alguna de las modalidades contempladas en la Ley, en el ámbito del Estatuto de los Trabajadores y en los Convenios Colectivos a los que pertenezca la actividad que se desarrolle (investigación, docencia, o cualquier otra)
Retrieval of Solar Shortwave Irradiance from All-Sky Camera Images
Get PDFThe present work proposes a new model based on a convolutional neural network (CNN) to retrieve solar shortwave (SW) irradiance via the estimation of the cloud modification factor (CMF) from daytime sky images captured by all-sky cameras; this model is named CNN-CMF. To this end, a total of 237,669 sky images paired with SW irradiance measurements obtained by using pyranometers were selected at the following three sites: Valladolid and Izaña, Spain, and Lindenberg, Germany. This dataset was randomly split into training and testing sets, with the latter excluded from the training model in order to validate it using the same locations.The research has been supported by the Ministerio de Ciencia e Innovación, with the grant no. PID2021-127588OB-I00, and the Junta of Castilla y León with the grant no. VA227P20. This work is part of the project TED2021-131211B-I00 funded by MCIN/AEI/10.13039/501100011033 and European Union, “NextGenerationEU”/PRTR. This research is based on work from COST Action CA21119 HARMONIA, supported by COST (European Cooperation in Science and Technology)
