The circulation of the atmosphere is characterized by features such as polar fronts, mid-latitude jet streams (fast-flowing narrow air currents) and a tropical meridional (north–south) overturning ...

Though scientists have long understood how lightning strikes, the precise atmospheric events that trigger it within thunderclouds have remained a perplexing mystery. The mystery may now be solved, ...

We analyze the characteristics of atmospheric variations over tropical South America using the pattern recognition framework of weather typing or atmospheric circulation patterns (CPs). During ...

Earth's tropical regions drive some of the most powerful weather and climate variability globally. Among these, the ...

Scientists may have to rethink the relationship between the ocean's circulation and its long-term capacity to store carbon, new research suggests. As the ocean gets weaker, it could release more ...

Changes in atmospheric circulation under increasing greenhouse gas concentrations are important because of their implications for weather extremes and associated societal risks. However, uncertainties ...

Pedro DiNezio receives funding from NSF. One of the big contributors to the record-breaking global temperatures over the past year – El Niño – is now gone, and its opposite, La Niña, is on the way.
