Wind Analysis

Calm Sector: The central circle of the wind rose, often referred to as the "calm sector," indicates the percentage of time (e.g., 39%) during which no wind or only minimal wind movement was recorded.

Wind Directions: The wind rose diagram is divided into 16 segments, each representing a wind direction of 22.5°. Below is a description of the wind directions:

• 0° - N (North): -> Short bar, low wind frequency, primarily low wind speeds (3-6 knots)

• 22.5° - NNE (North-Northeast): -> Very short bar, almost no wind from this direction

• 45° - NE (Northeast): -> Barely any wind from this direction; the bar is almost invisible

• 67.5° - ENE (East-Northeast): -> Similar to NE, no significant wind frequency

• 90° - E (East): -> Slightly visible bar, low wind frequency (3-6 knots)

• 112.5° - ESE (East-Southeast): -> Almost no wind from this direction, very short bar

• 135° - SE (Southeast): -> Nearly no wind from this direction; bar is minimal

• 157.5° - SSE (South-Southeast): - > Very short bars, minimal wind activity

• 180° - S (South): -> Few winds from this direction; bars visible for 3-6 knots

• 202.5° - SSW (South-Southwest): -> Slight activity, dominated by low wind speeds

• 225° - SW (Southwest): -> One of the dominant wind directions; longer bars with various speed ranges (up to 15-20 knots)

• 247.5° - WSW (West-Southwest): -> Noticeable activity, primarily low to moderate wind speeds (6-15 knots)

• 270° - W (West): -> Dominant direction, longer bars, with a concentration of 6-15 knots and some stronger winds

• 292.5° - WNW (West-Northwest): -> Significant wind frequency, bars with moderate speeds (up to 10-15 knots)

• 315° - NW (Northwest): -> Less wind from this direction, mainly low speeds (3-6 knots)

• 337.5° - NNW (North-Northwest): -> Low wind frequency, visible bars for low wind speeds

Wind Speed: The wind intensity is illustrated by the color of the bars. Different colors represent various wind speed ranges:

• Light gray: 3–6 knots

• Dark gray: 6–10 knots

• Light blue: 10–15 knots

• Dark blue: 15–20 knots

• Red: More than 20 knots

Percentage Frequency: The length of the bars represents the percentage of time the wind came from a specific direction. Longer bars indicate higher frequency

Analysis Details:

• The location is displayed above the diagram, along with the height at which the wind analysis was conducted

• The analysis period is shown at the bottom right, along with the coordinates of the analysis location

Y-Axis: The Y-axis represents the percentage of time during which the wind speed/direction fell within a specific speed/direction range.

Speed Bins:

• 0–3 knots (light gray)

• 3–6 knots (medium gray)

• 6–10 knots (dark gray)

• 10–15 knots (blue)

• 15–20 knots (dark blue)

• 20+ knots (red)

Direction Bins:

• 0° to 330° (in 30° increments)

• Colors vary to clearly differentiate the individual directions, e.g.:

  • 0° (North) in blue

  • 90° (East) in green

  • 180° (South) in red

  • 270° (West) in brown

X-Axis (Hours in UTC): Displays the hours of the day (in UTC) from 0 to 23.

Analysis Details: The analysis location, time period, and the considered time of day are noted at the bottom of the diagram.
