Going from architecture to training

Extreme dry and humid heat events show distinct seasonality often not aligned with meteorological summer, even in the tropics Extreme heat seasons have expanded since the 1980s over about half of...

The speed of sound, Snell’s Law and the FAA

High-resolution simulations reveal that direct carbon dioxide effects nonlinearly amplify positive low-cloud feedbacks.

Zeke Hausfather had an interesting post recently at The Climate Brink on what drove early 20th Century warming, suggesting it was a roughly equal mix of human activity, natural forcings (volcanoes) an...

Researchers warn the high-pressure conditions could disrupt marine life and ecosystems if it continues

As the weather becomes less predictable, we need forecasts and apps that are better at telling us what we don’t know.

We present a method for low-cost emulation of spatially resolved natural temperature variability at monthly resolution The emulator output's statistical, spatial, and temporal characteristics res...

Our new study shows what happens when contrail avoidance is built directly into the tools airlines already use.

Blue ice records from Antarctica are used to determine methane and carbon dioxide concentrations over the past 3 million years.

An analytical model for CO2 ${\text{CO}}_{2}$’s surface forcing is developed, incorporating the 667 and 1000 cm−1 bands Surface forcing is non-monotonic and peaks at relatively cool surface tempe...

An analytical model is presented for the lifecycle of tropical anvil cloud radiative effects, including for cloud spreading The model reproduces the cloud radiative effect lifecycle seen in a clo...

Variability and trends in ERA5 downward surface shortwave radiation agree well with high-quality in situ and satellite-based estimates Recent (1980–2024) trends in shortwave over land largely ali...

This AIGFS forecast in the form of a map, for December 10, 2025, shows the heavy precipitation from an atmospheric river hitting the U.S. Pacific Northwest. AI weather models like this one will protect life and property by improving forecast accuracy and timeliness for events such as the catastrophic flooding that impacted the Northwest.

A tripolar pattern of Pacific sea surface temperature variability strongly modulates tropical cyclone latitudes and largely determined their poleward migration during the period 1980–2024, according t...
