• NASA Satellites Peer into a Lop-sided Hurricane Maria

    NASA’s Aqua satellite and Global Precipitation Measurement mission, or GPM, satellites have been peering into what appears to be a somewhat lop-sided Hurricane Maria. The storm appears asymmetric because vertical wind shear is pushing clouds and showers to the eastern side of the storm.

    On Sept. 27, NHC forecaster Daniel Brown noted, “Deep convection and banding has increased over the eastern and northeastern portion of the large circulation of Maria since yesterday.”

  • Climate Change: Some Lessons From the Vikings

    One June day in the year 793, men in ships landed on Lindisfarne, an island off eastern England occupied by a monastery. The men, apparently from the north, plundered treasures, overthrew altars and set fire to buildings. They killed some monks and carried others off in chains; others, they stripped naked and left behind to the mercies of the weather. The attack shocked European Christian society. They came to mark it as the official start of the Viking Age, when Norse raiders ranged as far as the southern Mediterranean and northern Asia, before seemingly fading out some 250 years later.

  • Large iceberg breaks off Pine Island Glacier

    Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica’s Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

  • Long-term weather forecasting a guessing game

    Famous for its weather forecasts, the Old Farmer’s Almanac has published its predictions for the coming year—but don’t believe everything you read.

    The folksy pocket-sized magazine has been a regular go-to for farmers and other fans during fall harvest season since it first began publishing in 1792. As cosy and comforting as pumpkin pie, it offers everything from home remedies to food recipes—but the long-range weather predictions that fill many of its pages are nothing but pure guesswork, said a University of Alberta weather modelling expert.

  • Arctic sea ice at minimum extent for 2017

    Arctic sea ice extent has likely reached its minimum extent for the year, at 4.64 million square kilometers (1.79 million square miles) on September 13, 2017, according to a team of international scientists. The 2017 minimum is the eighth lowest in the 38-year satellite record. The Arctic sea ice minimum marks the day – typically in mid-September – when sea ice reaches its smallest extent at the end of the summer melt season.

  • Deep waters spiral upward around Antarctica

    Since Captain James Cook’s discovery in the 1770s that water encompassed the Earth’s southern latitudes, oceanographers have been studying the Southern Ocean, its physics, and how it interacts with global water circulation and the climate.

  • NASA Satellite Temperatures Reveal a Stronger Hurricane Lee

    NASA's Aqua satellite peered into Hurricane Lee with infrared light to determine if the storm was intensifying. Infrared data showed cloud top temperatures were getting colder, indicating stronger storms.

  • NASA Satellite Data Shows Hurricane Maria's Strongest Side

    NASA's Aqua satellite provided an infrared look at Hurricane Maria's cloud top temperatures and found the coldest cloud tops and strongest storms were facing east of the center and away from the U.S. However, Maria is a large hurricane. On Sept. 26, the National Hurricane Center reported that hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm-force winds extend outward up to 240 miles (390 km).
