Studies, Reports, and Data

Wrisk Consulting LLC provides a wide range of studies and reports featuring products derived from analyses of selected meteorological, metocean, and hydrometeorological parameters and conditions worldwide.

Our comprehensive metocean data, studies, and reports focus on defining and explaining the historical behaviors of winds, waves, ocean currents, and other environmental parameters. We analyze central tendencies, means, and extremes at any location across the globe. Each study and report is tailored to its purpose, incorporating relevant elements such as detailed data, XY analysis tables, distribution roses, line graphs, scatterplots, focused commentaries, and climate narratives to qualify and quantify long-term environmental behaviors for a specific location or geographic region.

Some of our most common studies and reports include, but are not limited to:

Some of our more common studies and reports include, but are not limited to:

Corresponding Wind and Wave Study and Report
  • Description: Focuses on comparisons of X vs. Y variables, such as:
    • 10-meter Wind Direction vs. 10-meter Wind Speed
    • Mean Wave Direction vs. Mean Wave Period
    • Mean Wave Direction vs. Significant Wave Height
    • Significant Wave Height vs. Mean Wave Period
    • Ocean Current Direction vs. Ocean Current Speed may also be requested and added
    • Any X-Parameter vs. Any Y-Parameter
  • Output:
    • Corresponding tables and distribution roses that indicate the relationships between variables.
    • Graphs depicting scalar variable data plots over time, including means, trends, and standard deviations.
    • Original data sets used in the study.
    • Extreme Wind and Wave Study and Report
    • Description:
      This study focuses on extreme value analyses of winds, waves, or other requested variables. It employs two methods:
      • Block Maxima: Data extremes are fit to a Generalized Extreme Value (GEV) distribution.
      • Peaks Over Threshold: Declustered data extremes are fit to a Generalized Pareto Distribution (GPD).

      Results from both methods are evaluated using statistical goodness-of-fit tools. Additional variables, such as swells, ocean currents, and temperatures, can also be analyzed. The original data used in the study is included in the report.

      Output:

      • Tables showing return periods (e.g., 100-year, 50-year, etc.) and return levels.
      • Probabilities of exceedance and non-exceedance for selected environmental variables.
    Comprehensive Wind and Wave Study and Report

    • Description: Combines the Corresponding Wind and Wave Study and the Extreme Wind and Wave Study to provide a complete assessment of environmental conditions at a specific location.

      Output: Includes all products from both the Corresponding Wind and Wave Study and the Extreme Wind and Wave Study, along with the original data used in the analyses.

    Tropical Cyclone Risk Analysis Study and Report

    • Description: Provides detailed tropical cyclone analysis tables and charts characterizing the daily, monthly, and annual long-term occurrences, probabilities, and return periods of tropical cyclones at or near a specified location or area. Analyses include systems passing within 75 and 150 nautical miles of the selected location or region.

      Output: Includes tables of tropical cyclone statistics, such as monthly and annual frequencies, probabilities, and return periods for tropical storms, hurricanes, and major hurricanes. The original data used in the study is also provided.
