Modeling Precipitation: Evaluation in Oceanic Extratropical Cyclones using IMERG 4 October 2019

Modeling Precipitation: Evaluation in Oceanic Extratropical Cyclones using IMERG

With precipitation in the midlatitudes predominantly produced in extratropical cyclones, research efforts have strived to find new ways of evaluating and analyzing model precipitation errors. However, due to the sheer number of processes involved in the production of precipitation, it is a difficult parameter to model.

Can atmospheric patterns help predict coastal flooding? 6 September 2019

Can atmospheric patterns help predict coastal flooding?

A new study shows significant potential in using atmospheric patterns to forecast coastal flooding that occurs without rainfall during high tides.

Coupling Land and Lake Models to Improve Climate Forecasts 3 September 2019

Coupling Land and Lake Models to Improve Climate Forecasts

Over the last several decades, climate models have significantly improved due to enhancements in technology and data. However, producing reliable climate forecasts remains a challenge due to the climate models’ inability to include local and mesoscale land and atmospheric processes. 

Could El Niño Break the Global Mean Surface Temperature Record in the 21st Century? 26 August 2019

Could El Niño Break the Global Mean Surface Temperature Record in the 21st Century?

Causing unusually warm waters off the coast of Central and South America, an El Niño event refers to a large scale ocean and atmospheric interaction that results in the warming of sea surface temperatures across the Equatorial Pacific. 





 

How Well Do Models Forecast MJO Propagation? 19 August 2019

How Well Do Models Forecast MJO Propagation?

The Madden-Julian Oscillation (MJO) is an eastward moving disturbance of clouds, rainfall, winds, and pressure located in the tropical longitudes, which can drive atmospheric circulation around the planet. On average, this atmospheric disturbance travels across the tropics and returns to its initial starting point every 30 to 60 days.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
