Powerful New Software Helps Expedite Weather and Climate Forecasting Improvements

Weather and climate models are an essential part of predicting extreme weather events and projecting future changes in climate. Since these models can enable better disaster preparedness and reduce risks related to extreme weather, it is important to ensure that their simulations include limited bias or error.

Researchers Investigate Historical and Future Risk of Rain-on-snow Flooding Events

In NCEI’s database of billion-dollar flooding disasters, many of the most significant events occur in the late Winter or early Spring due to rain and snowmelt overcoming stream and river channel capacity. These events individually frequently reach $5-10 billion in damages.

Scientists Explore Cutting-Edge Multi-Year ENSO Forecasts Using Climate Model

The authors show that there is the potential to extend 12-month operational forecasts of El Niño and La Niña events by one additional year.
Are the unprecedented 2019 Southcentral Alaska Fires a result of anthropogenic climate change? 12 February 2021

Are the unprecedented 2019 Southcentral Alaska Fires a result of anthropogenic climate change?

In 2019, a prolonged drought and unusual high summer temperature induced an unprecedented fire season in Southcentral Alaska. The following questions would arise: Is the 2019 disaster attributed to anthropogenic climate change? Do we expect more fire seasons in the future in Southcentral Alaska like 2019?
