Sea surface temperature biases shift the North Pacific jet stream southward, study finds

Climate models are numerical models used to project future climate change. 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. Understanding the causes and impacts of present-day climate biases is therefore important for improving the reliability of future climate projections.
