Determination of the Jenkinson and Collison’s weather types for the western Mediterranean basin over the 1948-2009 period. Temporal analysis

Assessment of an extended version of the Jenkinson–Collison classification on CMIP5 models over Europe

“…Further details about the procedure for classifying the types can be found in Jones et al 1993. The JC classification has been applied to different grid resolution, 5° × 5° (Trigo and DaCamara 2000), and other configurations of points (Dessouky and Jenkinson 1977;Spellman 2000;Grimalt et al 2012). According to the original catalogue, Unclassified days are reallocated with a threshold for total flow and vorticity, which might be readjusted for a specific region (Goodess and Palutikof 1998;Conway et al 1996).…”

“…Previous studies found a significant increase of portion of Unclassified days in summer and autumn when applying JC classification. Particularly, in the Iberian Peninsula this was attributed to the low-pressure gradient that characterises this area during those seasons (Goodess 2000;Grimalt et al 2012).…”

“…This classification, originally developed for the British Isles, has been one of the most prominent WT classification schemes applied in mid-high latitudes. An extensive number of studies that use the JC procedure can been found in the literature and they have mainly focused on Europe: Trigo and DaCamara (2000), Linderson (2001), Goodess and Jones (2002), Spellman (2000), Chen (2000), Grimalt et al (2012), Lorenzo et al (2008), Post et al (2002), Buishand and Brandsma (1997), Cortesi et al (2013), among others. Besides these areas, this scheme has been applied in other regions where it has been rarely used so far, such as USA (Wilby et al 1995), China (Liwei et al 2006), Taiwan (Lai 2010), Chile (Espinoza et al 2014), the Arabian Peninsula (El Kenawy et al 2014), or Russia (Spellman 2015).…”

Meteorological Patterns Linked to Landslide Triggering in Asturias (NW Spain): A Preliminary Analysis

“…The most widely used methods are the Lamb weather type classification [23], the Jenkinson and Collinson system [24] or the COST733 weather synoptic types [25]. In other cases, the classification of weather types is performed through a multivariate analysis, especially Principal Component Analysis [26].…”

Clima, sociedad, riesgos y ordenación del territorio

“…Para el ámbito de la Península Ibérica puede usarse el retículo octogonal de 16 puntos, P01, P02, P03,…,P16 de la figura 1, cuyos puntos son intersecciones de los paralelos 30º, 35º, 40º, 45º y 50ºN con los meridianos10ºE, 0º, 10ºW y 20ºW, exceptuando los vértices del retículo. Podrían usarse otros retículos (Grimalt et al, 2013). Conociendo la presión atmosférica en superficie en los 16 puntos, sean, usando la misma notación, P01, P02, P03,…,P16, se hallan los valores de las 7 variables.…”
