An asymmetry in the clustering of oceanic surface material has been observed at submesoscales. Energetic and ephemeral submesoscale cyclonic fronts are associated with convergence zones, hence cluster material. Their anticyclonic counterparts do not feature such an effect. Yet, mesoscale, literature contradictory about asymmetry. Here, we combine drifter trajectories altimetry-derived mesoscale...

Abstract Extra-tropical continental summer heatwaves often occur under persistent anticyclones or blocking. Here we partition heatwave changes into contributions from blocking changes, heatwave–blocking relation change and mean temperature increase, global warming in climate models. We employ an optimized index that best correlates with (Pearson correlation of 0.7) find heatwave-driving decreas...

While most precipitation in Antarctica falls as snow, little is known about liquid precipitation, although it can have ecological and climatic impacts. This study combines meteorological reports at 10 stations with the ERA5 reanalysis to provide a climatological characterization of rainfall occurrence over Antarctica. Along East Antarctic coast, occurs 22 days per year coincides maritime intrus...

Abstract The Jovian InfraRed Auroral Mapper (JIRAM) onboard the NASA Juno mission monitored evolution of Jupiter’s polar cyclones since their first observation ever in February 2017. Data acquired by JIRAM have revealed cloudy organized a complex, yet stable geometrical pattern at both poles. Several studies investigated dynamics and structure these cyclones, to understand physical mechanisms b...

A comparative assessment of the contribution eddies and other dynamic structures to energy Lofoten Basin is carried out. The basis study data global ocean reanalysis GLORYS12V1 for 1993–2019. We estimate total kinetic potential as well corresponding eddy a region bounded by an isobath 3000 m. use method automatic identification vortices analysis which allows us calculate in automatically select...
