New research investigated the influence of extreme solar particle events on the Earth’s ozone layer and climate, concentrating on how these events interact with varying geomagnetic field strengths and providing crucial insights into possible hazards to human health and ecological stability.
On July 30, 2024, NIWA reported that the anomalies from the recent stratospheric warming have started to propagate downward and are affecting tropospheric weather patterns in the southern hemisphere.
The Southern Annular Mode (SAM) has started shifting into its negative phase this week, likely caused by a recent sudden stratospheric warming (SSW) event over Antarctica, which is expected to bring colder and wetter conditions to southern Australia.
A massive Saharan dust plume reached South Florida on July 20, 2024, causing reduced air quality and hazy skies. Rain is also forecasted for the weekend, and the mix of dust and precipitation is expected to bring dirty rains to Florida.
A rare Sudden Stratospheric Warming (SSW) event has been detected in the stratosphere above the Antarctic region over the past week. Forecast models predict it will start to filter down through the atmosphere later this month.
The display of unusual noctilucent clouds (NLCs) continues to light up the European skies on July 13, 2024, with another large outbreak seen all over the continent, leading to some stunning visuals.
The unexpected display of noctilucent clouds all over Europe since June 23, 2024, has given rise to a couple of speculations as to why are these clouds forming during a solar maximum when high solar activity inhibits their formation.
The largest outbreak of Saharan dust this summer is currently making its way across the Atlantic Ocean, potentially impacting air quality and weather patterns throughout the Caribbean and parts of the United States. This marks a significant shift in the season’s weather patterns, influenced by the Saharan Air Layer (SAL), which is known for its ability to suppress tropical cyclone formation.
On June 23, 2024, Europe experienced an unexpected outbreak of noctilucent clouds (NLCs) despite high solar activity, which typically inhibits NLC formation. Earth-orbiting satellites also detected the display, noting NLCs down to a latitude of 55° N over the British Isles.
The third large wave of Saharan dust in just two weeks is moving over Europe, significantly increasing PM10 concentrations at ground level for the Iberian Peninsula, and some parts of France and Germany.
