The passage of weather fronts over southeast Australia during the spring and summer increases the risk of dangerous fire weather. This project will carry out an analysis of observational data to determine a method for characterising when fronts have passed through southeast Australia.
Climate sensitivity describes how sensitive the Earth’s temperature is to a doubling of the amount of carbon dioxide in the atmosphere. One measure of climate sensitivity for projections of future climate is the Equilibrium Climate Sensitivity (ECS). ECS is the increase in the global average temperature between the pre-industrial era and a future doubled carbon dioxide climate once equilibrium of the climate has been reached.
It has been remarkable how much we have achieved in this extraordinarily difficult year. Research coming out of the Teleconnections and Variability program over the past four months has strongly focused on how influences in one part of the world can have direct impacts on another.
CLEX researchers find rapidly intensifying hurricanes may become more frequent in a future warmer climate and the speed of this increase in intensity will continue to accelerate as the world's oceans continue to warm.
CLEX and NCAR researchers explore decade-long variations in global mean temperature that are superimposed on the warming trend and find what can make short term warming trends so unpredictable.
All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.
This paper is a review article that stemmed from a debate within the Southern Ocean community. The paper explains how “fronts”, sharp boundaries between water masses, are defined, and what their effects might be on the biology of the Southern Ocean.
Overview The ocean has absorbed 93% of global warming heat. This service by the ocean to life on Earth has not been without consequence. The oceans are warming rapidly, ocean species are being displaced and sea level rise threatens many coastal communities. The pathway for heat to enter the deep ocean is primarily through dense water formation in the North Atlantic and around Antarctica. This large-scale conveyor from the surface to the deep ocean is known as the Meridional Overturning... View Article
CLEX researchers and colleagues revisit the quasi-equilibrium analytical framework introduced by Comins and McMurtrie (1993) and explore the consequences of specific model assumptions for ecosystem net primary productivity (NPP).
New work published in Nature Communications develops a correction method that ensures the probability of climate extremes in the model simulations are consistent with real-world observations. In addition, it also corrects the rate of the long-term changes and the inter-annual variability so that it is consistent with observations.
