Correcting Fast-Mode Pressure Errors in Storm-Scale Ensemble Kalman Filter Analyses

Figure 7

True (left column), retrieved (middle column), and EnKF mean posterior (right column) 𝑝 (top row), 𝜕𝑝/𝜕𝑥 (middle row; hPa km⁻¹), and 𝜕𝑝/𝜕𝑧 (bottom row; hPa km⁻¹) at 𝑧=0.9 km, 𝑡=50 min. The true 𝑝 were filtered and averaged as in Potvin et al. [23] to permit more direct comparisons with the (coarser) EnKF 𝑝. Radar reflectivity factor is contoured at 10, 30, and 50 dBZ.
