- ENSO index teleconnection with seasonal precipitation in a temperate ecosystem of northern Mexico MARÍN POMPA-GARCÍA XANAT ANTONIO NÉMIGA Biología MEI ext Niño 3 tree rings Pinus cooperi El Niño Southern Oscillation (ENSO) is the most important large-scale circulatory phenomenon that causes climatic variability in northern Mexico. The current challenge is to understand its consequences for both local climate and ecological processes of ecosystems. Within this context, we compared the degree of association of three different ENSO indices with local seasonal precipitation ( P ) in northern Mexico, and used dendrochrono - logical series (tree-ring chronologies [TRI]) of Pinus cooperi to assess the impact of forest growth. The results showed a strong association between ENSO, previous winter precipitation and TRI ( r > 0.5, p = 0.05), indicating a positive relationship between warm ENSO phases and subsequent tree growth. The multivariate ENSO index was slightly better at explaining the connection between P and radial growth than other indices. These results could be used to support further research on the effects of ENSO on local climate and forest ecosystems. 2015 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56532983004 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.1 Vol.28
