New link may offer 5-week lead time on predicting extreme heat in California’s fruit belt.
Antarctica’s Seasonal Streams Contribute Iron to the Ross Sea
Analysis of nutrient concentrations in four streams that discharge to the Southern Ocean indicates they are important sources of iron and phosphorous for coastal phytoplankton communities.
Using Multiple Models to Improve Seasonal Forecasting
The first study to examine the ability of a suite of general circulation models to predict sudden warmings in Earth’s stratosphere highlights the potential for improving Northern Hemisphere forecasts.
How Yellowing Seas Will Affect Ocean Temperatures
Materials that trap solar heat at the sea surface could cause more extreme temperatures.
Take Weather Prediction with a Grain of Salt and It Gets Better
Sea surface salinity is starting to rival other methods for seasonal rain forecasting.
The Ice Nurseries of the Arctic Are Melting
Ice formed in coastal nurseries along Russia’s Arctic coast is melting before it can float far offshore. Scientists are worried about what that means for wildlife.
