**Preface to "Climate and Atmospheric Dynamics and Predictability"**

The state of the weather and climate is largely defined by the interactions between the various components of the climate system (atmosphere, hydrosphere, land surface, cryosphere, biosphere). The understanding and the prediction/projection of the atmospheric and climate dynamics (i.e., how the natural laws determine the weather and climate) are essential for life, property and environment. High-impact weather systems, low-frequency oscillations and their climatic variability exert a significant influence on humans and their activities. Over the last few decades, the advances in weather and climate numerical models and the increase of computational resources have resulted in a blooming of weather forecasting and climate research, allowing for more effective planning and preparedness against adverse weather and climate change.

This Special Issue was mainly devoted to collecting observational, theoretical and modeling studies on the dynamics of the atmosphere and the climate system, as well as on their predictability at different spatiotemporal scales.
