Antarctic climate exhibits large variability with increasingly widespread signals of externally-forced change emerging. In such a rapidly evolving system is it more important than ever to continuously monitor the state of the Antarctic climate system in near real time. Due to the strong interactions between different components of the system, it is important that a range of diagnostics are considered.
AntClimNow Antarctic Climate Indicators
Westerly Jet Latitude and Speed Indices
Jet latitude index is a measure of the latitudinal position of core of the westerly winds blowing over the Southern Ocean.
Surface Mass Balance (SMB)
Surface mass balance can be thought of as a balance of the gain and loss on the surface of the Antarctic Ice Sheet.
Atmospheric River Events
The dataset provides atmospheric river (AR) shapes south of 50ºS latitude.
Stratospheric Polar Vortex Index
This dataset captures the variability of stratospheric polar vortex in the Southern Hemisphere (SH).
Zonal Wave 3
The dataset documents the variability in one of the major zonally asymmetric atmospheric circulation features in the Southern Hemisphere extratropics, the Zonal wave 3 pattern.
