Focus on:• Remote sensing measurements• over the central and eastern North 

Atlantic• operate from Iceland

Primary aims:• thermodynamic properties in outflow of 

WCBs, at jet level• humidity structure of lower troposphere• diabatic influence on upper level flow, 

observations in divergent outflow regions• follow evolution of Rossby waves along 

the wave guide• combined lidar/radar observations• Preparation of ADM satellite validation

1. Moisture Structure in the Boundary layer: What is the structure and evolution of low level moisture flowing into mid‐latitude cyclones?

2. Mixed phase clouds: What are the roles of microphysical and embedded dynamical processes to air mass modification in Warm Conveyor Belts?

3. Upper level PV: Can we approximate PV from synergistic use of temperature and wind data to identify diabatically generated anomalies?

4. Diabatic effects on cyclonic systems: What are the distinct cloud, wind and thermodynamic structures that characterize diabatically intensified cyclones?

5. Impacts of tropopause waveguide uncertainty on HIW events: How much do small errors at jet‐level cause uncertainty in downstream extreme weather?

6. Moisture and Cloud Structure in Tropopause Region: How do tropopause‐level temperature, moisture and cloud gradients influence radiative heating?

7. Quantification of analysis errors: How well are diabatic modifications to mid‐latitude cyclones represented in operational analysis and forecast products? 

The overarching scientific hypothesis of NAWDEX : "Diabatic processes over North America and the North Atlantic have a major influence on jet stream meanders, the downstream development of Rossby waves on the tropopause and high impact weather over Europe.”
