Earth’s climate is characterized by persistent westerly jets (eastward flow) in the upper troposphere, located in the mid-latitudes of the Northern and Southern Hemisphere, which are associated locally with strong weather systems. The location of these jets is of paramount importance to human societies, as these are collocated with maximum in precipitation rates and surface winds in the extratropical regions.

Public discussions of climate change often focus on greenhouse gases and rising temperatures, but the most severe and immediate societal impacts of global warming are likely to be associated with changing hydrological conditions. Disruptions in water supply, extreme storms and record droughts may impact every aspect of rural and urban society: from agriculture and manufacturing to housing, energy and human health.
