This study investigates the exceptional heatwaves of 2022 in the Pyrenees, focusing on their physical drivers and environmental influences. The June heatwave was advective in nature, with stronger mountain-induced circulations resulting in heterogeneous temperature anomalies, while the July event had subsiding and weaker atmospheric flow, leading t...
Identifying water supply tensions between competing users in extreme future scenarios: a case study from the Pyrenees
The Pyrenees, as well as other mountainous areas, are the main source of fresh water for the lowland regions but also include high water-consuming areas. The context of global change leads to spatiotemporal changes in water availab...
This paper describes the main outcomes of the European research project MOMPA (Monitoring of Ground Movements and Action Protocol). Its objective is to provide useful tools for the prevention and management of risks due to slope movements, based on the satellite monitoring InSAR (Interferometric SAR) technique. The project includes two parts: risk...
Precipitations processes at windward and leeward sides of the mountains have been object of study for many decades. Instead, inner mountain valleys, where usually most mountain population lives, have received considerably less attention. This article examines precipitation processes during a winter field campaign in an inner valley of the Pyrenees...
Co-financed by the Interreg V Program in Spain-France-Andorra (POCTEFA) the European project MOMPA (MOnitoring of ground Movements and Action Protocol) study the landslide hazard in the Eastern Pyrenees. It groups together scientific partners from CTTC (Telecommunications Centre of Catalonia), ICGC (Cartographical and Geological Institute of Catalu...

Mountain systems within the Mediterranean region, e.g., the Pyrenees, are very sensitive to climate change. In the present study, we quantified the magnitude of extreme precipitation events and the number of days with torrential precipitation (daily precipitation ≥ 100 mm) in all the rain gauges available in the Pyrenees for the 1981-2015 period, a...

On 8th February 1996, in the north-western part of Andorra in the Pyrenees, the Les Fonts d’Arinsal (LFd’A) pure powder avalanche was triggered, descending some 1200 m to the bottom of the Arinsal valley and continuing up the opposite slope for about 200 m. This size 4–5 avalanche reached velocities of up to 80 ms−1, devastated 18 ha of forest, inv...
The 15 January 2017 a strong northerly synoptic flow lead to the generation of mountain waves and heavy snowfall over the eastern Pyrenees, particularly over the Cerdanya valley near the border between France, Spain and Andorra. Measurements from several instruments deployed during the Cerdanya-2017 field campaign and satellite imagery revealed the...
CLIMPY (Characterisation of the evolution of climate and provision of information for adaptation in the Pyrenees) is a transboundary project that aims to perform a detailed analysis of recent trends in temperature, precipitation and snow cover in the Pyrenees, and their future projection. As a result, changes in the frequency, intensity, spatial ex...
Recent studies reported that precipitation and mountain waves induced low tropospheric level circulations may be decoupled or masked by greater spatial scale variability despite generally there is a connection between microphysical processes of precipitation and mountain driven air flows. In this paper we analyse two periods of a winter storm in th...
Under the umbrella of the CLIM'PY project (Intereg programme - POCTEFA 2014-2020), this research shows the main climatic trends for temperature (both maximum and minimum) and precipitation over the whole Pyrenees, at annual and seasonal scale, and for the period 1950-2015.
The Pyrenees is a mountain range that presents a very broad range of climatic diversity, as well as a multitude of geographical factors conditioning precipitation in this region. In-depth knowledge of this precipitation, specifically of its association with atmospheric circulation types in mountain regions, is of great importance for the management...
Andorra is located in the axial Pyrenees, in a climatic transition zone (Atlantic-Mediterranean). Hence, different atmospheric circulation types generate a high variability on the spatial distribution of snowfalls and windstorms. This leads to episodes with different spatial patterns of avalanche activity affecting in a different way several ski re...
A survey on mountain behavior and perception of avalanche risk destined to winter activities practitioners has been carried out around the geographical area of Andorra. This survey has several objectives: on one hand, to identify the several groups of winter sports practitioners in Andorra, and on the other hand to compare the behaviors among peopl...
The CLIM’PY project (Characterization of the evolution of Climate and provision of information for adaptation in the Pyrenees) is a transboundary research project, including several public administrations, in which the current trends in temperature, precipitation and snow cover throughout the Pyrenees and its future projections are analysed
in deta...
Previous works using lower-density datasets addressed warming rates with slight differences depending on the season and diffuse trends for precipitation. New and more accurate results in spatio-temporal variations of these climate variables are expected on behalf the development of the CLIM’PY project, which aims to: i) detect past trends with inst...
In the framework of the GWOP’17 (Gravity Waves and Orographic Precipitation) project, we use
measurements from The Cerdanya-2017 field campaign to analyze episodes of mountain waves,
orographic precipitation and their associated processes over the Pyrenees. The Pyrenees is a
west to east oriented mountain range located along the border between Fran...
La Cerdanya is one of the largest valleys in the Pyrenees, singularly oriented ENE to WSW, 35 km long and 9 km wide. The bottom of the valley is about 1000 m above sea level and it is surrounded by mountain ranges rising to above 2900 m. This configuration makes the Cerdanya basin prone to the formation of Cold Air Pools (CAP). Also the alignment o...
Mountain areas are particularly sensitive to climate change. Species distribution models predict important extinctions in these areas whose magnitude will depend on a number of different factors. Here we examine the possible impact of climate change on the Rhododendron ferrugineum (alpenrose) niche in Andorra (Pyrenees). This species currently occu...
Winter potential snow accumulation map.
Winter potential snow accumulation calculated in Andorra following López-Moreno et al. (2007) using data from the Climatological Atlas of Andorra (Batalla et al. 2011). Dark blue tones indicate areas with high snow cover in winter and red areas indicate the current presence of the plant.

This study examines the effect of the orography on two heavy precipitation events (HPE1 and HPE2) which exceeded 100 mm in 24 h and affected the Eastern Pyrenees (Andorra, NE Spain and SE France) in the NW Mediterranean. High resolution simulations (3 km) performed with the Weather and Research Forecasting model (WRF) were compared with precipitati...
In the present study, we use a Principal Component Analysis (PCA) to characterize the surface 6-h circulation types related to substantial lightning activity over the Catalonia area (north-eastern Iberia) and the Principality of Andorra (eastern Pyrenees) from January 2003 to December 2007. The gridded data used for classification of the circulatio...
North episodes over the Pyrenees represent a challenge in terms of
forecasting associated effects, especially during the winter season.
Andorra, a small country located in the Pyrenees, between France and
Spain, is highly sensitive to these episodes. Usually these episodes
generate heavy snowfalls and intense windstorms which can substantially
incr...
In order to quantify the uncertainty of the radar-derived surface point quantitative precipitation estimates (QPE) from a regional radar network, a comparison has been made with a network of rain gauges. Three C-band Doppler radars and 161 telemetered gauges have been used. Both networks cover the area of Catalonia (NE Spain). Hourly accumulations...
