The polar vortex forming over the Northern Hemisphere in 2024 is at its weakest point for early October in the last 40 years, with potential consequences for winter weather patterns across North America and Europe. The vortex’s unusual behavior this season could lead to significant disruptions in cold outbreaks in parts of the eastern United States, Canada, and Europe.
Himawari satellite found a series of gravity waves moving towards northwestern Australia over the Indian Ocean on September 11 and 12, 2024.
The Antarctic ozone hole is growing anew. This annual phenomenon, set to peak in September and October, causes dangerous UV rays to penetrate the Earth’s atmosphere deeper. As the Southern Hemisphere enters spring, the ozone hole over Antarctica has started to form, leading to a significant depletion of ozone in the stratosphere. Monitoring has revealed…
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.
