Abstract
This is a summary of the southern hemisphere atmospheric circulation patterns and meteorological indices for spring 2018; an account of seasonal rainfall and temperature for the Australian region and broader southern hemisphere is also provided. A positive phase of the Indian Ocean Dipole developed during the season, and the central and eastern equatorial Pacific were warmer than average without reaching El Niño thresholds. It was Australia’s driest September on record, before rainfall of closer to average in October and November. It was warmer than average, especially in northern Australia, with coastal Queensland affected by extreme heat and wildfires in November. It was one of the three warmest springs on record for the southern hemisphere as a whole, and was notably dry in southern and eastern Africa.
期刊介绍:
The Journal of Southern Hemisphere Earth Systems Science (JSHESS) publishes broad areas of research with a distinct emphasis on the Southern Hemisphere. The scope of the Journal encompasses the study of the mean state, variability and change of the atmosphere, oceans, and land surface, including the cryosphere, from hemispheric to regional scales.
general circulation of the atmosphere and oceans,
climate change and variability ,
climate impacts,
climate modelling ,
past change in the climate system including palaeoclimate variability,
atmospheric dynamics,
synoptic meteorology,
mesoscale meteorology and severe weather,
tropical meteorology,
observation systems,
remote sensing of atmospheric, oceanic and land surface processes,
weather, climate and ocean prediction,
atmospheric and oceanic composition and chemistry,
physical oceanography,
air‐sea interactions,
coastal zone processes,
hydrology,
cryosphere‐atmosphere interactions,
land surface‐atmosphere interactions,
space weather, including impacts and mitigation on technology,
ionospheric, magnetospheric, auroral and space physics,
data assimilation applied to the above subject areas .
