The Sensible Heat Flux in the Course of the Year at Ny-Ålesund, Svalbard: Characteristics of Eddy Covariance Data and Corresponding Model Results

Figure 5

Kinematic sensible heat flux eddy covariance versus sensible heat flux HMA (30 min averages, K m s−1), separated for the three wind sectors “normal” (20°–150°, marked with black dots), “disturbed” (150°–270°, marked with pink dots), and “synchronisation” (270°–20°, marked with blue dots). Additionally shown are the linear regression equations for the different sectors (colour-coded) for data from the convective period: (a) for the time window 16.6. to 31.8. and friction velocities ≤0.23 m s−1, (b) for the time window 16.6. to 31.8. and friction velocities >0.23 m s−1, (c) for the time window 1.9. to 15.6. and friction velocities ≤0.23 m s−1, and (d) for the time window 1.9. to 15.6. and friction velocities >0.23 m s−1.
