The climate system
A climate ensemble is the group of different
climate models used to simulate the future climate
based on the same emission scenario.
The aggregated ensemble simulations are
expected to be more robust than individual model
runs.

A climate index is a diagnostic quantity that is
used to characterize and quantify an aspect
of a geophysical system.
For instance:
• How many tropical nights will we have per
year?
• How will the frequency of dry spells per
year evolve from now?
• How intense will the annual maximum 1-
day precipitation be by 2050?
