Mapping the Mozambique Channel
The Mozambique Channel boasts some of the world’s most turbulent waters, driven by eddies hundreds of kilometers wide. Eddies of this size — known as mesoscale — determine regional flows that influence local biodiversity, sediment mixing, and how plastic pollution moves. To better understand the region, scientists measured a mesoscale dipole from a research vessel.
Illustration of flows in the Mozambique Channel. The anticyclonic ring in dark blue rotates counterclockwise and consists of largely uniform water (labeled Ring: R1). To the south, in green, a cyclonic eddy rotates in a clockwise sense (labeled Cyclone: C1). This area is chlorophyll-rich and has varying salinity levels. Between the two is a filament of chlorophyll-rich water being drawn from the near-shore region (labeled Filament: F1).The dipole consisted of a large anticyclonic ring (shown in dark blue) that rotated counterclockwise and a smaller cyclonic eddy (shown in green) that rotated clockwise. Between these eddies lay a central jet moving up to 130 centimeters per second that drew material out from the shoreline. In the anticyclonic ring, researchers found largely uniform waters with little chlorophyll. The cyclonic eddy, in contrast, was high in chlorophyll and had large variations in salinity. Those smaller-scale variations, they found, helped to drive vertical motions of up to 40 meters per day.
In situ measurements like these help scientists understand how energy flows through different scales in the ocean and how that energy helps transport nutrients, sediment, and pollution regionally. Such measurements also help us to refine ocean models that enable us to predict this transport and how regions will change as climate patterns shift. (Image credit: ship – A.

Potentially historic tornado outbreak in the south today. Environmental conditions only this favorable once before. Be safe.

"Warmer air holds more moisture for a longer time. So it may not rain for some days, then suddenly dump a month’s worth of rain in a few hours.
#Nowcasting is basically extrapolation based on clouds and other observations. Radars provide us high resolution, infrared images. Models are also used. That is enough to tell us what to expect in the next few hours. We are increasingly seeing #mesoscale events during monsoon periods which have a very localised impact.”
In a new #GJI paper, Mendieta et al. explore the effect of #mesoscale heterogeneities on macroscopic #SIP measurements on non-consolidated clay material ⚡️🪨
