The two emission-reduction scenarios proposed in this Programme (WEM: With Existing Measures and WAM: With Additional Measures) were simulated with the chemistry transport model CHIMERE (v2013) at a resolution of approximately 8 km × 8 km for a domain covering the Iberian Peninsula and Balearic Islands. The year 2021 was simulated as a reference scenario, using the reported annual emissions in the Spanish National Emission Inventory and the meteorology from the European Centre (ECMWF IFS) for the same year. Also, the sensibility to other factors, such as the model version, the driving meteorology and the chemical mechanism, was evaluated by using a different version of CHIMERE (v2017), different modelled meteorology (WRF), different meteorological years and a different chemical mechanism (SAPRC-07 instead of MELCHIOR2).

It pretends to be a point of focus on information related to the subject and to be a tool to get a quick and updated look of space weather. At this page we can inspect the current status of solar activity related to flares, solar energetic particles (SEP) flux, solar wind, magnetosphere, ionosphere and geomagnetic activity.

Análise de casos de estudo Autor : Serpa, Pedro; Bugalho, Lourdes; Ramos, Ricardo; Silva, Pedro Resumen : The HDW index was implemented by IPMA in 2023 as an experimental product. Given it’s novelty, in order to build up knowledge and gain sensitivity over the index temporal and spatial variability the index climatology was computed for the period 1990-2022 and the results analyzed. As a complement of this analysis the index was evaluated during forest fire events in Portugal. This work will present the HDW index surface climatology and it’s behavior during the two biggest forest fires that occur in Portugal Mainland in 2023: the Sarzedas and Odemira forest fires. The climatology was computed using ERA5 reanalysis data. The case studies were performed using hourly data from the ECMWF model, 9 km resolution, and the AROME, 2.5 km resolutions, for comparison purposes. The HDW behavior during these events were analyzed at the surface and at pressure levels.

However, the direct effect of global warming on wildfires is hard to quantify due to the multiple non-climatic factors involved in their ignition and spread. By combining wildfire observations with the latest generation of climate models, we show that in more than half of the large wildfires (area>500 ha) that took place in the Iberian Peninsula between 2001 and 2021 there is a significant increase in the rate of spread with respect to what it would have been in the pre-industrial period, attributable to global warming. The influence of enhanced vegetation growth on the increase in the rate of spread since the pre-industrial period could potentially be even higher than that of the temperature increase. We also show that other parameters associated with wildfire behaviour, such as heat release or flame length, also show the same climate change-induced amplification effect.
