here. As water vapor is the overwhelming dominant greenhouse gas,
climate modelers and climate scientists are just starting to research
water vapor's process and impact. Another reason why climate models are
so unsuccessful at climate predictions.
- Although the mechanisms are not well understood, it is widely appreciated that heating and cooling of air through phase changes of water are integral to moist convection and dynamics in the equatorial region. But that water vapor plays an active and important role in dynamics globally is less widely appreciated, and how it does so is only beginning to be investigated.
