WebNov 15, 2012 · The results indicate that the leading modes of July precipitation variations in Northwest China are affected by the Silk Road pattern and the Europe–China (EC) pattern. The analysis suggests that the circumglobal teleconnection (CGT) could be considered as the interannual component of the Silk Road pattern. WebRecent research has led to improvements in European winter seasonal forecasts (e.g. Scaife et al., 2011; Dunstone et al., 2016) however there has been less of a focus on the summer season and so summer forecast skill remains relatively low. The European climate is affected by a large range of influences, including from tropical regions, and better …
