Cobertura nival y distribución de las temperaturas en el suelo en las cumbres de la Sierra de Guadarrama

Abstract

RESUMEN. El trabajo muestra el resultado de la monitorización de la temperatura del aire y del suelo en el período 2002-2007, en las proximidades de la cumbre del Alto de las Guarramillas (2.258 m; 40°47' 10'' N y 3°58' 46'' W) ABSTRACT. Air and ground temperatures were monitored from 2002-2007 at the summit area of Alto de las Guarramillas (2258 m; 40°47' 10'' N and 3°58' 46'' W)

Ground and Near-Rock Surface Air Thermal Regimes in the High Mountain of the Picos De Europa (Cantabrian Mountains, NW Spain)

“…In other places in the Asturian Massif, such as the Gistredo Massif and Peña Prieta, Santos-González et al (2009) detected a maximum of 12 to 27 FTCs per year between 2003 and 2007, at similar depths (10–15 cm) and at altitudes between 1940 and 2280 m. In other Iberian mountain ranges, such as the Sierra de Guadarrama, the number of days with soil temperature oscillations below and above 0°C fluctuated between 2 and 41 during the years 2002 to 2007, at the same depth as in the present study (10 cm) and at 2,212 m altitude (Andrés & Palacios Estremera, 2010).…”

“…In the same way as Castañón and Frochoso (1998) and González-Trueba and Serrano (2010) in their studies of the Central Massif, the results of this study show a low thermal amplitude in the FTCs, which also tend to last only between one and a few days (short duration cycles). Although they have been rare, longer FTCs have also been recorded, with negative In other places in the Asturian Massif, such as the Gistredo Massif and Peña Prieta, Santos-González et al (2009) detected a maximum of 12 to 27 FTCs per year between 2003 and 2007, at similar depths (10-15 cm) and at altitudes between 1940 and 2280 m. In other Iberian mountain ranges, such as the Sierra de Guadarrama, the number of days with soil temperature oscillations below and above 0°C fluctuated between 2 and 41 during the years 2002 to 2007, at the same depth as in the present study (10 cm) and at 2,212 m altitude (Andrés & Palacios Estremera, 2010).…”

“…This methodology has been widely used in the last two decades, both in mountain areas and in polar zones, in order to establish the relationship between periglacial landforms and processes, and temperature regimes (e.g. Andrés & Palacios Estremera, 2010; Andrés et al, 2010; Castañón & Frochoso, 1998; González-Trueba & Serrano, 2010; Matsuoka, 2006; Melón-Nava et al, 2022; Salvador-Franch et al, 2010; Santos-González et al, 2009; Serrano et al, 2020; Serrano et al, 2019a); to determine the existence or non-existence of permafrost, and the evolution of associated forms (e.g. Gómez-Ortiz et al, 2001; Hoelzle et al, 1999; Ishikawa, 2003; Kneisel, 2010; Luetschg et al, 2004; Lugon et al, 2004; Melón-Nava et al, 2022; Serrano et al, 2001, 2010), and even to examine the effects of soil temperature on the composition and distribution of vegetation (e.g.…”

“…Other Iberian mountainous environments, such as the Sierra de Guadarrama in the Iberian Central Range (e.g. Andrés & Palacios Estremera, 2010; Muñoz-Jiménez et al, 2007) and the Cantabrian Mountains, have also been studied in this sense. In the Cantabrian Mountains, in the last decades significant progress has been made in the knowledge of the active periglacial dynamics of the highest areas (e.g.…”

Snow cover as a morphogenic agent determining ground climate, landforms and runoff in the Valdecebollas massif, Cantabrian Mountains

“…Nevertheless, most contributions to date on the Central Cantabrian Mountains have focused on the search for active processes Frochoso, 1994, 1998;Serrano and González-Trueba, 2004b;González-Trueba, 2007a;Santos-González et al, 2009;González-Trueba and Serrano, 2010b;Santos-González, 2011;Pellitero, 2013;Pisabarro et al, 2015Pisabarro et al, , 2017 and conclude that snow cover is the driver of freeze-thaw cycles (F/Tc) and seasonal frozen grounds (SFG). In this sense, the study of the ground thermal regime (GTR) facilitates the understanding of the capacity of the climate to trigger active periglacial processes and shows it to be a good indicator of snow cover characteristics (Zhang, 2005;French, 2007;Ballantyne, 2018), particularly in the Mediterranean mountains (Vieira et al, 2003;Andrés and Palacios, 2010;Oliva et al, 2014Oliva et al, , 2016 where the snow cover is highly variable in time because of the climatic characteristics of this region.…”
