Polar cyclones on Jupiter create a spellbinding vortex cluster

Jupiter’s north pole is a swirling mass of cyclones, and their mesmerizing dance was recently captured in astonishing detail in images from JunoCam, the visible light camera/telescope on NASA’s Juno orbiter. The Juno mission, launched on Aug. 5, 2011, has been collecting data on Jupiter since 2016. Juno recently completed its 29th orbit of the […]

How Tropical Cyclones Increase in Intensity Overnight

In recent years, there has been increasing interest in the diurnal cycle of tropical cyclone characteristics. Wu et al. [2020] analyze the diurnal variations in the intensity of tropical cyclones using satellite data of convective clouds. While tropical cyclone intensity has no significant variation, they showed that there is a nocturnal tropical cyclone […]

When Cyclones and Conflicts Collide

Relationships between extreme weather and subsequent violence can be fiendishly complex to disentangle. But these links are becoming increasingly relevant as weather extremes become more frequent because of climate change. A new project led by two U.S. researchers is tackling one important question: What impact do tropical cyclones have on armed conflict? Cyclones […]

Post-Tropical Cyclones Influence on European Windstorm Risk

Atlantic hurricanes that transition into midlatitude storms at high latitudes can affect Europe, in some cases leading to high-impact windstorms. Sainsbury et al. [2020] compared the climatology and intensity distributions of post-tropical cyclones and midlatitude storms impacting Europe (separated into northern and southern Europe) during the Atlantic hurricane seasons from 1979 to 2017 […]

Tropical cyclones moving faster in recent decades: study

Credit: CC0 Public Domain About 40% of the U.S. population lives in a coastal area and in Hawai’i, nearly everyone is vulnerable to the effects of tropical storms and hurricanes. Tropical cyclones, regionally known as hurricanes or typhoons, have been moving across ocean basins faster since 1982, according to a new study published in Environmental […]
