UNDERSTANDING THE REGIONAL AND FINE SCALE ASPECTS OF WEATHER AND CLIMATE

View our forecasts

The Mesoscale and Microscale Meteorology Laboratory (MMM) aims to benefit
society by increasing an understanding and knowledge of the mesoscale (1–1000
km) and microscale (10-6 – 1000m) aspects of weather and climate.

MMM collaborates with other National Center for Atmospheric Research (NCAR) labs
to improve Earth-system predictability through researching the process and
prediction surrounding mesoscale and microscale atmospheric phenomena. MMM also
plays a central role in the atmospheric simulation capability across NCAR.

OUR MODELS

We strive to produce the most accurate and effective computational models, data
assimilation systems, and representations of unresolved weather and climate
model processes


WEATHER RESEARCH & FORECASTING MODEL (WRF)

A state of the art mesoscale numerical weather prediction system designed for
both atmospheric research and operational forecasting applications

MODEL FOR PREDICTION ACROSS SCALES (MPAS)

Atmosphere, ocean and other earth-system simulation components

Learn More


RESEARCH SECTIONS

We are focused on improving the ways in which we communicate atmospheric
processes and predictions, in order to help others understand how advances in
atmospheric science will benefit society


CAPACITY CENTER FOR CLIMATE & WEATHER EXTREMES

Identifying the multi-scale Earth System processes that drive high-impact
weather on sub-seasonal to climate timescales.


DYNAMICAL & PHYSICAL METEOROLOGY SECTION

Carries out basic and applied research on atmospheric phenomena spanning a wide
range of scales


PREDICTION, ASSIMILATION & RISK COMMUNICATION SECTION

Studies advanced techniques for data assimilation and probabilistic weather
forecasts, and the intersections between weather hazards and society


WEATHER MODELING & RESEARCH SECTION

Advancing research and development in mesoscale meteorology and numerical
weather prediction


GEOPHYSICAL TURBULENCE PROGRAM

Promote research, education and awareness of geophysical turbulence at NCAR and
in the scientific community. Pages for historical purposes only


OUR FORECASTS

We utilize collaborations within NCAR and throughout the community to achieve
more accurate mesoscale weather forecasts and climate prediction and
projections. View our real-time forecasts below from various model output


WRF FORECASTS

The current WRF forecasts for the weather today including precipitation, 100-500
hPa thickness, wind, and severe storm potential

AMPS FORECASTS

Producing numerical guidance with twice-daily forecasts covering Antarctica

HRRR FORECASTS

Neural Network Convective Hazard Forecast probability of any severe hazard
within 40 km

REAL TIME FORECASTS

Real-time forecasts produced with MPAS, WRF, IFS, and GFS models
