The analysis of Tropical Cyclone Cristina's cloud top temperatures revealed some bands of thunderstorms were developing and wrapping around the center of the storm's circulation.
When NASA's Aqua satellite passed over Tropical Storm Cristina in the Eastern Pacific Ocean on July 8, it gathered water vapor data that provided information about the intensity of the storm.
A low-pressure area strengthened quickly and became Tropical Storm Cristina in the Eastern Pacific Ocean and infrared imagery from NASA revealed the powerful thunderstorms fueling that intensification.
When NASA-NOAA's Suomi NPP satellite passed over the western North Atlantic Ocean on July 6, it provided forecasters with a visible image of Edouard after it transitioned into a post-tropical cyclone.
Air pollution during the COVID-19 lockdown in Beijing was mainly due to different chemical responses of primary and secondary aerosols to changes in anthropogenic emissions.
New particle formation (NPF) over three countries is investigated using aerosol physicochemical quantities and turbulence information. A common relationship is found between NPF and turbulence, and a new physical mechanism is proposed to complement the traditional photochemical mechanism, supported by both observational analyses and model simulations. Turbulence enhances supersaturation, accelerating the condensation of molecules, and facilitating nucleation formation, while the turbulence-dilution effect prevents the removal of preexisting particles, prolonging the growth of NPF.
The latest tropical storm in the Atlantic Ocean formed one day ago and was already being battered by wind shear. NASA's Aqua satellite imagery revealed Tropical Storm Edouard's strongest storms were being displaced by strong southwesterly winds.
Tropical Depression 4E formed late on June 29 and it is forecast to become a remnant low-pressure area by the end of the day on June 30. NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the depression, located just southwest of the southern tip of Mexico's Baja Peninsula.
NASA-NOAA's Suomi NPP satellite imagery provided a look at the end of the second named tropical cyclone of the Eastern Pacific Ocean's 2020 Hurricane Season.
New research indicates that significant enhancement of secondary aerosol formed in the atmosphere via gas-to-particle conversion, together with long-lasting regional transport, may be the cause of severe haze over China despite a dramatic reduction in emissions during the COVID-19 shutdown. The findings are published in Geophysical Research Letters.
