Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

August 3, 2020 4:48 pm Published by Comments Off on Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

CLEX researchers used real-world observations with satellite observations to calculate the quantity of nutrients carried into the Subantarctic Zone by mesoscale eddies. They found these eddies carried high nitrate and low silicate waters into the Subantarctic Zone.

Research brief: How salty seawater can tell us whether to expect rain

July 10, 2020 1:10 pm Published by Comments Off on Research brief: How salty seawater can tell us whether to expect rain

Ocean salinity could be an indicator of major rain events before IOD or ENSO events have peaked. This raises the prospect that long term forecasts for Australia could be improved by analysing sea surface salinity in the Indian and Pacific oceans.

Research brief: New Metrics for Assessing Small Scale Wind Processes in Bureau Forecasts

July 9, 2020 9:59 am Published by Comments Off on Research brief: New Metrics for Assessing Small Scale Wind Processes in Bureau Forecasts

In this paper, CLEX researchers developed new metrics to assess whether forecaster edits targeting these processes were reducing error in the daily varying component of the wind forecasts, by comparing edited and unedited forecast data with weather station observations.

Research brief: The shortcomings of convection-resolving models

July 3, 2020 3:53 pm Published by Comments Off on Research brief: The shortcomings of convection-resolving models

A new paper by Martin Jucker and colleagues reveals the choice of a particular convection-resolving model (CRM) has a much larger impact on the results than increasing resolution. It also suggests the behaviour of CRMs is tied to model internals instead of the phenomena they are trying to reproduce.

Research brief: Natural variations shift rain-bearing winds south

June 30, 2020 10:46 am Published by Comments Off on Research brief: Natural variations shift rain-bearing winds south

CLEX researchers found the influence of climate change and the depletion in stratospheric ozone are the major drivers over the Atlantic Oceans that shift westerly winds further south. However, over the Pacific and Indian oceans natural variations induced by sea surface temperature changes in the tropical Pacific also play an important role.

Research brief: Cold air below thunderstorms affects storm orientation

June 22, 2020 3:47 pm Published by Comments Off on Research brief: Cold air below thunderstorms affects storm orientation

This study investigates the influence of cold pools, which are evaporatively cooled regions of air near the surface, below thunderstorms, on the orientation of line‐organized thunderstorm clusters using computer model simulations.
