Climate change will expand the range of tropical cyclones, making millions more people vulnerable to these devastating storms, a new study says. Therefore, it is expected that improvement in the reproducibility of atmospheric circulations at high latitudes would contribute to improved accuracy of severe weather forecasts for the mid-latitudes, even in summer.

The focus of this chapter is cyclonic storm systems that form in the mid-to-high latitudes outside of the tropics. Using seconds of latitude, global positioning system (GPS) devices can pinpoint schools, houses, even rooms in either of these towns. An ensemble data assimilation system called ALEDAS236, which comprises the atmospheric general circulation model for the Earth Simulator (AFES)37,38 and local ensemble transform Kalman filter (LETKF)39, produced the AFES-LETKF experimental ensemble reanalysis version 2 (ALERA2) dataset.

A report by the Intergovernmental Panel on Climate Change advised that coral reefs worldwide are projected to decline by a further 70-90 per cent at a 1.5C increase in temperature, with greater losses at a 2.0C increase.
