Polar jet streams are typically located near the 250 hPa (about 1/4 atmosphere) pressure level, or seven to twelve kilometres (23,000 to 39,000 ft) above sea level, while the weaker subtropical jet streams are much higher, between 10 and 16 kilometres (33,000 and 52,000 ft). Jet streams wander laterally dramatically, and change in altitude.
The large amount of glacial meltwater flowing into the eruption vent made this eruption so explosive that it ejected its ash plume directly into the jet stream, which was unusually stable and south-easterly. [11] The ash was then carried over Europe into some of the busiest airspace in the world.
Map all coordinates using OpenStreetMap. The 37th parallel north is a circle of latitude that is 37 degrees north of the Earth's equatorial plane. It crosses Europe, the Mediterranean Sea, Africa, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. At this latitude the Sun is visible for 14 hours, 42 minutes during the summer ...
Rossby wave. Meanders of the Northern Hemisphere's jet stream developing around the northern polar vortex (a, b) and finally detaching a "drop" of cold air (c). Orange: warmer masses of air; pink: jet stream; blue: colder masses of air. Rossby waves, also known as planetary waves, are a type of inertial wave naturally occurring in rotating ...
Topography of Europe. Some geographical texts refer to a Eurasian continent given that Europe is not surrounded by sea and its southeastern border has always been variously defined for centuries. In terms of shape, Europe is a collection of connected peninsulas and nearby islands. The two largest peninsulas are Europe itself and Scandinavia to ...
North Atlantic Current. The North Atlantic Current is the first leg in the North Atlantic Subpolar Gyre. The North Atlantic Current (NAC), also known as North Atlantic Drift and North Atlantic Sea Movement, is a powerful warm western boundary current within the Atlantic Ocean that extends the Gulf Stream northeastward.

According to luxury travel agency Virtuoso, a growing number of wealthy travelers plan to venture to major cities like New York, Rome, and Paris in the fall of 2024 compared to 2023.
Floods started in Belgium, Germany, the Netherlands, and Switzerland on 14 July 2021 after record rainfall across western Europe caused multiple rivers to burst their banks. [15] The European Flood Awareness System (EFAS) issued alerts of life-threatening floods in advance, which, although very vague, were delivered to national authorities.
