Title:
Coupled ADCIRC+SWAN simulations of Lake Superior with surface ice cover in February 2020
Abstract:
The analyses of the Great Lakes Environmental Research Laboratory's (GLERL) historical ice cover data during 1973–2021 indicate that warmer winters with reduced surface ice cover have become more frequent in the last two decades (1995–2021) compared to the previous decades (1973–1995) in the Great Lakes. In the past two decades, for example, years with lower-than-normal ice cover have become more frequent in Lake Superior, which has a history of freezing almost completely. These observations suggest a possible regime shift to a lower-ice state for this lake. It is hypothesized that the transition to a lower-ice state in the next decades may have significant implications for coastal hazards such as wave-induced coastal erosion and flooding, depending on surface ice-wave interactions and their possible effects on Lake Superior's hydrodynamics. The literature; however, lacks any effort that analyzes Lake Superior’s surface ice-wave interactions, resulting in limited knowledge on the dynamics of these interactions within this and similar lakes. In this regard, a set of numerical simulation were carried out using the coupled circulation and spectral wave model, ADCIRC (v55.01) +SWAN (41.31AB), to investigate the contribution of surface ice to lake-wide hydrodynamics, wave power, and wave runup in Lake Superior. Simulations specifically focused on the year 2020, known for its comparatively reduced surface ice cover in recent years, and the ice-wave interactions were quantified for February, the month with the largest surface ice cover. The coupled model was forced with Great Lakes Coastal Forecasting System (GLCFS) hourly wind field data, National Centers for Environmental Prediction Forecast System, version 2 (CFSv2) atmospheric pressure, GLER surface ice concentration, and U.S. National Ice Center (USNIC) thickness. The lake bathymetry used in the simulations was obtained from NOAA GLERL.
Supplemental_Information:
It was not possible to directly evaluate the model’s accuracy in predicting the lake wide hydrodynamics for February since the wave buoys were out of the lake from November to late April due to surface ice formation. To address this issue, additional simulations were carried out for a three-month-long period when buoy data are available, i.e.,from August to November, 2020. The coupled ADCIRC+SWAN model was then validated against several sets of measurements obtained from the NOAA water level stations and NDBC wave buoys within Lake Superior. Then, the validated model was used to simulate the lake wide hydrodynamics for February, 2020.

Why was the data set created?

This set of simulations were carried out to investigate the contribution of surface ice to lake-wide hydrodynamics, wave power, and wave runup in Lake Superior.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 01-Jun-2023 (process 1 of 1)
    The following steps were performed by Erdinc Sogut:
    1) The following data were collected from the followings: i) The lake's bathymetry was acquired from the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL) web page (https://www.ncei.noaa.gov/products/great-lakes-bathymetry). ii) Great Lakes Coastal Forecasting System (GLCFS) hourly wind field data was gathered from NOAA Thredds server (https://www.ncei.noaa.gov/thredds/catalog/model-lsofs-files/catalog.html). iii) National Centers for Environmental Prediction (NCEP) Forecast System, version 2 (CFSv2) hourly atmospheric pressure data was obtained from NOAA Thredds server (https://www.ncei.noaa.gov/thredds/catalog/model-cfs_v2_anl_ts/catalog.html). iv) Daily surface ice cover data was obtained from GLERL web page (https://www.glerl.noaa.gov/data/ice/#historical). v) Daily surface ice thickness data was obtained from U.S. National Ice Center (USNIC) web page (https://usicecenter.gov/Products/GreatLakesData).
    2) The model input files fort.13 (Nodal Attributes File), fort.14 (Grid and Boundary Information File) and fort.15 (Model Parameter and Periodic Boundary Condition File) were generated by using the open source MATLAB toolbox OceanMesh2D (Roberts, K. J., & Pringle, W. J., 2018; https://github.com/CHLNDDEV/OceanMesh2D).
    3) Atmospheric pressure (fort.221), wind (fort.222) and ice field (fort.225) files were generated in Oceanweather Inc. (OWI) format from the data collected at step-1 using MATLAB.
    4) fort.26 (SWAN runtime parameters) was adjusted for the study area.
    5) The performance of the coupled ADCIRC+SWAN model in predicting lake-wide water levels and wave dynamics (Hs: significant wave height, Tp: peak wave period, and Dir: average wave direction) were assessed for a three-month-long ice-free period, i.e. August to November 2020 due to lack of field observations in February 2020. The model predicted water levels and wave dynamics were compared with the data of five NOAA water level stations and three National Data Buoy Center (NDBC) wave buoys to quantify the model accuracy.
    6) fort.22 (Meteorological Forcing Data) wind speed factor adjusted to minimize model error for the three-month-long ice-free period.
    7) Following the successful completion of the validation process, a set of numerical simulations, one ice-free (IF) and six ice-on (M14, D15, R18, M18, H20, and R21) models, were carried out. In February, ADCIRC model was only forced with SIC due to the model constraints. On the other hand, SWAN model was forced with surface ice concentration (for M14, R18 and H20) and thickness (D15, M18, and R21). The fort.221, fort.222, and fort.225 files created in step 3 were used as meteorological forcing for both the ice-free and ice-on models without any modifications. No adjustment was performed for wind speed in fort.22.
    8) Water levels, wave dynamics, and wave spectrum were extracted from the model outputs using MATLAB. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The root mean square error (RMSE), mean absolute error (MAE), and Index of Agreement (IA; Willmott, 1981) metrics were used to quantify the model skills in replicating meteorological forcing, lake-wide water levels and wave dynamics (Hs: significant wave height, Tp: peak wave period, and Dir: average wave direction) during a three-month-long ice-free period, i.e. August to November 2020.
    i) Atmoshperic pressure had a moderate accuracy (IA ≈ 0.45) contrary to the wind speed and direction, which had very good skill scores (IA > 0.95). Even though the IA values for atmospheric pressure were low, it could still be used as a model forcing because the deviations in the RMSE (≤ 11.43 hPa) and MAE (≤ 9.06 hPa) values were relatively small.
    ii) Even though the simulated water levels had moderate accuracy (IA ≈ 0.5), they deviated from the measured quantities a few cms—RMSE values ranged between 3.5 cm and 9.3 cm and MAE values ranged between 2.8 cm and 7.7 cm.
    iii) The coupled ADCIRC+SWAN model performed well, IA > 0.95, in generating wave dynamics.
  2. How accurate are the geographic locations?
    Forcings: 1) Great Lakes Coastal Forecasting System (GLCFS) hourly wind field data, which has a grid resolution of 0.09 deg latitude × 0.13 deg longitude (~10 km × ~14.5 km) and covers the entire lake area 2) National Centers for Environmental Prediction (NCEP) dynamics Forecast System, version 2 (CFSv2) pressure data which is available on a Gaussian grid with a mesh resolution of 0.5 deg ×0.5 deg (~55 km × ~55 km) 3) Great Lakes Environmental Research Laboratory historical surface ice concentration with a mesh resolution of 0.010 deg latitude × 0.016 deg longitude (~1.1 km × ~1.8 km). 4) U.S. National Ice Center (USNIC) daily analysis of surface ice thickness on Gaussian grid with a mesh resolution of 0.025 deg × 0.025 deg (~2.8 km × ~2.8 km)
    Mesh: The mesh containing 185,770 vertices and 348,800 triangular elements has a maximum mesh resolution of 1.25 km offshore, which is then refined to 100 m nearshore to provide better resolution for the wave-transformation zones.
    Tests: 1) mesh resolution of 2.5 km offshore, which is then refined to 250 m nearshore: the model skills in replicating meteorological forcing, lake-wide water levels and wave dynamics was < 0.5 2) mesh resolution of 1.25 km offshore, which is then refined to 100 m nearshore: the model skills in replicating meteorological forcing, lake-wide water levels and wave dynamics was > 0.5 3) mesh resolution of 1.25 km offshore, which is then refined to 50 m nearshore: the model skills in replicating meteorological forcing, lake-wide water levels and wave dynamics was > 0.5
    Refining mesh size to 50 m nearshore does not significant improved the model skill but the simulation duration was increased. Therefore, mesh size (2) was selected.
  3. How accurate are the heights or depths?
    The model outputs are based on the International Great Lakes Datum (IGLD, 1985) low-water datum which is 183.2 m.
  4. Where are the gaps in the data? What is missing?
    Any missing data is marked as NaN.
  5. How consistent are the relationships among the observations, including topology?
    The results are specific to model configurations adopted, as well as the wind, atmospheric pressure, surface ice concentration, and thickness forcings utilized in the simulations. Modifying the model parameter in the input files or using other sources for model forcings might lead to variations in the model's predicted lake-wide water levels and wave dynamics.
