Research brief: Southern Ocean vortices are changing
The energy of vortices in the Southern Ocean has increased over the past two decades due to an increase in the mean amplitude of the vortices rather than an increase in their number.

Research brief: Inexpensive innovation improves Ensemble Kalman filter
A known weakness of the Ensemble Kalman filter approach is that its ability to provide state estimates that closely match densely distributed observations is very limited. This paper describes a computationally inexpensive innovative variation on the technique that greatly ameliorates this difficulty.

Research brief: Rescuing centuries-old meteorological measurements
This paper documents the efforts of the international weather data rescue initiative ACRE, the International Surface Temperature Initiative and researchers that took part in workshops held in Bern, Switzerland, in June 2018 to rescue and digitize meteorological measurements taken prior to 1850 from around the world.

Research brief: Gravity waves cause unusual turbulence
This research uses commercial aircraft data and high-resolution simulations to study a case in 2005 over the United States where severe turbulence was encountered about 50km away from a large mesoscale convective system. Of relevance, current aviation turbulence avoidance guidelines recommend avoiding storms by 32 km (20 miles).

Research brief: How heat in the Indian Ocean moves between the ocean and atmosphere
In this study, CLEX researchers use two years of measurements from a flux mooring combined with satellite data and model outputs to understand the seasonal changes in air‐sea fluxes and the role of ocean currents in controlling ocean surface temperatures in the southeast Indian Ocean.

Research brief: Wind changes over the Southern Ocean impact its capacity to take up carbon and heat
CLEX researchers and colleagues examined the movement of surface water into the depths of the ocean in response to these wind changes using a global ocean model.

Research brief: Future directions for the Indian Ocean Observing System
This paper reviews the societal and scientific motivations, current status, and future directions of IndOOS, while also discussing the need for enhanced observations in priority areas.

Research brief: Tagged seals unlock secrets of eddy driven transport in Antarctica
Observations from Antarctic seals fitted with scientific instruments have revealed how eddy driven transport may be driving the melting of ice shelves, with consequent impacts on sea-level rise.

Research brief: Climate model projections of Philippines typhoon activity
The Philippines is one of the most exposed countries in the world to tropical cyclones. In order to provide information to help the country build resilience and plan for a future under a warmer climate, researchers built on previous research to investigate implications of future climate change on tropical cyclone activity in the Philippines.

Research brief: Phosphorus poor soils halve Amazon’s ability to take up carbon dioxide
This study showed that phosphorus availability reduced the projected CO2-induced biomass carbon growth by about 50% over 15 years compared to estimates from carbon and carbon-nitrogen models.
