A wavelet‐based method for the assessment of hydrodynamic model behavior against observed sea level variability

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sea level outputs from hydrodynamic models are often assessed against tide gauge data by comparing the standard deviations of modeled and observed time series, and by calculating the Pearson correlation coefficient and centered root mean square error (cRMSE) between the two.

Storage duration and water type determine the need for mercury chloride preservation of dissolved inorganic carbon

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract To quantify aquatic carbon budgets, it is important to accurately measure dissolved inorganic carbon (DIC). The standard approach requires the use of mercury chloride (HgCl2) poison to preserve samples, but the real need and overall constraints of using such a toxic compound remain elusive. Here, we evaluate the need for filtration and mercury

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

New views of some invariants associated with the Cartesian 2D velocity gradient tensor

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Vorticity and divergence of horizontal flow are fundamental quantities in meteorology; both are linear functions of the four elements of the 2D velocity gradient tensor and both are formally unchanged under coordinate rotation. We explore four quadratic functions of the elements that are geometrically invariant in this sense, finding some novel ...
