the climate change signal in the CCSM (the same CCSM simulation downscaled in NARCCAP). This result (Bukovsky and Karoly 2011) is encouraging in providing a robust explanation for the difference in direction of change between a GCM and RCM for summer precipitation, when the influence of large scale

rainfall average of 125 mm during this year. Despite this weather lore proving untrue, phenology records such as those presented in this report are a very valuable contribution to monitoring and understanding the influence of variations in climate on aspects of nature that we can all observe

Defence and security partnerships Weather and environmental conditions influence almost all military activities, affecting people, platforms, weapons and sensors. For more than 100 years, the Met Office has supported defence and security operations by providing critical weather and climate
