New research looks to improve prediction of brief but intense rainstorms that can cause devastating flash floods and landslides. Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.

A potentially monster winter storm is shaping up and will impact the East Coast beginning Friday through Saturday night. The general weather situation hints at …

Last summer's Western North American heat dome caused more than record-breaking temperature increases--rising anxiety about climate change is reported in a new study on the weather event's impact on our mental health.

Taking into account a variety of trees and green structures in four otherwise similar residential courtyards, a new study evaluates their effects on thermal comfort, biodiversity, carbon storage and social interaction. The authors show that those courtyards with more green structures yield considerably better results than those with fewer, and in their cooling capacity have a significant impact on people's thermal comfort.

Computer simulations of snow cover can accurately forecast avalanche hazard, according to a new international study. Currently, avalanche forecasts in Canada are made by experienced professionals who rely on data from local weather stations and on-the-ground observations from ski and backcountry ski operators, avalanche control workers for transportation and industry, and volunteers who manually test the snowpack.

Extreme rainfall events associated with atmospheric rivers, narrow bands transporting large amounts of moisture in the atmosphere, are becoming more frequent and severe in mountainous parts of East Asia as the climate changes. According to global and regional climate models comparing historical trends with a future scenario of 4 degrees of warming of global-mean surface air, these events are likely to become more frequent and intense in the future, especially in the Japanese Alps region.

Economic growth goes down when the number of wet days and days with extreme rainfall go up, a team of scientists finds. The data analysis of more than 1,500 regions over the past 40 years shows a clear connection and suggests that intensified daily rainfall driven by climate-change from burning oil and coal will harm the global economy.

Clouds have significant impact on the energy balance of the Earth system. Low clouds such as Stratocumulus, Cumulus and Stratus cover about 30 percent of the Earth surface and have a net cooling effect on our climate. What counteracts global warming, can have economic consequences: a persistently dense and low cloud cover over land can reduce agricultural production and the solar-power generation. Understanding the factors governing low cloud cover is not only important for regional weather forecasting and global climate prediction but also for their socioeconomic effects.

Researchers show that the increase of sea ice surrounding Antarctica since 1979 is a unique feature of Antarctic climate since 1905 -- an observation that paints a dramatic first-ever picture for weather and climate implications on the world's southernmost continent.

Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, a study has found. In 2020, more than 68% of the western U.S. -- representing about 43 million people -- were affected in one day by the resulting harmful-levels of air pollution, the highest number in 20 years. The study found that these concurrent air pollution events are increasing not only in frequency but duration and geographic extent across the region. They have become so bad that they have reversed many gains of the Clean Air Act. The conditions that create these episodes are also expected to continue to increase, along with their threats to human health.
