North Atlantic warming hole impacts jet stream

The North Atlantic warming hole (NAWH), a region of reduced warming located in the North Atlantic Ocean, significantly affects the North Atlantic jet stream in climate simulations of the future, according to a team of researchers.

Sea surface temperatures (SST) are projected to increase in most of the world’s oceans as the result of global climate change. However, within an area of rotating ocean currents just south of Greenland an anomaly exists where colder sea-surface temperatures were documented in both global climate-model projections and in observations. It’s called a hole because there is a lack of ocean warming.

This region of the ocean is a really important place for forcing the jet stream that goes across the North Atlantic Ocean. Jet streams, high altitude currents of wind flowing above the Earth, transport air masses and drive weather patterns. The relationship between climate change and jet streams is complex and understanding the potential impact of climate change on jet streams is crucial for understanding changes in weather patterns and storm tracks.

Living ‘Balloon on a String’

The depths of the Indian Ocean are home to some bizarre creatures — including one that looks like a balloon on a string. Explorers captured a video of this gelatinous creature in a recent dive to the Java Trench, the bottommost part of the Indian Ocean.

Volcanos

Global Volcanic Activity – New Activity for the week of 10 April – 16 April 2019

Asosan | Kyushu (Japan) : JMA reported an increase in the amplitude of volcanic tremor at Asosan on 14 April, increasing the possibility of an eruption at Nakadake Crater. The Alert Level was raised to 2 (on a scale of 1-5). Tremor amplitude further increased on 15 April. A very small eruption was recorded at 1828 on 16 April, producing a plume that rose 200 m above the crater rim and drifted NW.

Tengger Caldera | Eastern Java (Indonesia) : The Darwin VAAC reported that during 10-11 and 15-16 April ash plumes from Tengger Caldera’s Bromo cone rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted in multiple directions, based on webcam images and satellite data. The Alert Level remained at 2 (on a scale of 1-4), and visitors were warned to stay outside of a 1-km radius of the crater.

Villarrica | Chile : POVI reported that during 14-15 April lava fountains at Villarrica were visible rising as high as 70 m above the crater rim. Seismicity was low.
