TESTE DEIN WISSEN

CMIP

Lösung anzeigen
TESTE DEIN WISSEN

promises to produce a freely available state-of-the-art multimodel dataset
- designed to advance our knowledge of climate variability and climate change
- 20 climate modelling groups involved in development of CMIP5

Provides multimodel context for:
o Assessing new mechanisms of clouds and carbon cycle
o Examining climate predictability
o Determining why similarity forced models produce a range of responses
- CMIP5 strategy includes:
o long-term (century time scale) integrations
o near-term integrations (10–30 yr)

Typically gird cells with 100km on a side
- Typically several hundred years simulation

TESTE DEIN WISSEN

Nucleus for European Modeling of theOcean) is a 3-dimensional ocean model usedfor oceanography, climate modeling as well asoperational ocean forecasting. It includes othersub-component models describing sea-ice andbiogeochemistry.  Many processes are param-eterized, e.g.  convection and turbulence

TESTE DEIN WISSEN

Standardized Precipitation Index/Standardisierter Niederschlagsindex

based on precipitation and temperature data

allows for comparison of drought severity through time and space

involves a climatic water balance

multiscalar characteristics enable identification of different drought
types and effects in the context of global warming

Climate models

Lösung anzeigen
TESTE DEIN WISSEN

Climate models are based on a three-dimensional mesh covering the Earth and reaching high into the atmosphere. At regularly spaced intervals, or grid cells, the models use the laws of physics to compute atmospheric and environmental variables, simulating exchanges among gases, particles and energy.
Models can be used to simulate changes in climate over years,
decades, or even centuries.
• Climate models are based on fluid
mechanics and thermodynamics
