Sea surface temperature biases shift the North Pacific jet stream southward, study finds
Climate models are numerical models used to project future climate change.
Climate models are numerical models used to project future climate change.
The short version
- They simulate the climate from the present into the future by calculating changes in the atmosphere, ocean and other components of the climate system.
- However, simulations of the present-day climate do not perfectly reproduce observations and contain various biases.
- The model characteristics that cause these biases can also affect simulations of the future climate.
What happened
Understanding the causes and impacts of present-day climate biases is therefore important for improving the reliability of future climate projections. This article has been reviewed according to Science X's editorial process and policies .
Why it matters
Comparing these simulations, the team found that in 34 of 35 models, the westerly jet was located farther south when SSTs were simulated by the climate models than when observed SSTs were prescribed.
