DYNAMO campaign aircraft observations improve understanding of MJO

Research supported by NOAA CPO’s Climate Variability and Predictability (CVP) program has been accepted for publication in the Bulletin of the American Meteorological Society.

The paper by Chen et al., "Aircraft Observations of Dry Air, ITCZ, Convective Cloud Systems and Cold Pools in MJO During DYNAMO" examines the science outcomes of the many observations made by aircraft during the DYNAMO campaign.

The paper provides an overview of the observations that contributed to a better understanding of the interactions between convective cloud systems, environmental moisture and winds, air-sea fluxes, and convective cold pools. Several emerging science topics are presented that emphasize the importance of atmospheric water vapor variability as well as its connection to convective cloud systems and air-sea fluxes.

The observations are available online for future model analysis, including cloud-resolving and coupled model experiments and improvement projects.

The paper has not been published in a BAMS issue yet, but is available online in early release form: http://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-13-00196.1




Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
