What is a Windrose tool?

Introduction. A wind rose is a chart which gives a view of how wind speed and wind direction are distributed at a particular location over a specific period of time. ... The simple on line tool available in this web site allows to create wind roses with 16 directions, each one representing an arc 22.5 degrees wide.

What is a Windrose on a map?

The wind rose located in the top right corner of each data map shows the general wind direction and speed for each sampling period. The circular format of the wind rose shows the direction the winds blew from and the length of each "spoke" around the circle shows how often the wind blew from that direction.

What is the role of wind rose?

The modern wind rose used by meteorologists gives the percentage of the time the wind blows from each direction during the observation period; it sometimes shows the strengths of these winds and the percentage of the time calm air or light winds are observed.

How do you draw a Windrose diagram?

Draw a wind rose diagram for the following data.

1. Step 1: Select a suitable scale (in this case 1 cm = 10%)
2. Step 2: Draw a circle to represent the calm for this scale. ( ...
3. Step 3: Mark the directions in this circle using a protractor as shown in the figure.

Why is it called a wind rose?

Historically, wind roses were predecessors of the compass rose (found on charts), as there was no differentiation between a cardinal direction and the wind which blew from such a direction. ... The direction of the longest spoke shows the wind direction with the greatest frequency.

How do you make a Windrose?

To create a wind rose, average wind direction and wind speed values are logged at a site, at short intervals, over a period of time, e.g. 1 week, 1 month, or longer. The collected wind data is then sorted by wind direction so that the percentage of time that the wind was blowing from each direction can be determined.

Who Uses wind rose?

meteorologists A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location.

How do you convert degrees to directions?

To convert degrees to compass directions, I first divide the compass into 16 sectors of 22.5 degrees each. The sectors are like slices of pie, centered on the compass points. Tip: If you would like to use eight sectors instead of 16, with a shorter lookup table, divide by 45 degrees instead of 22.5 degrees.

How do you read a wind rose?

Wind roses are set up in a circle, just like a compass. When looking at one, the top represents north, the right represents east, the left west, and the bottom south. As a "spoke" extends along one of these directions, that indicates the wind was blowing from that direction, not toward it.

What is Rose plot?

The rose plot is a variation of the common pie chart. ... Pie charts and rose plots both use the area of segments of a circle to convey amounts. The pie chart uses a common radius and varies the central angle according to the data. That is, the angle is proportional to the frequency.

Which direction is WNW?

West-Northwest WNW = West-Northwest (282-303 degrees) NW = Northwest (304-326 degrees) NNW = North-Northwest (327-348 degrees)

What direction is 225 degrees?

Southwest The nearest of the eight directions is Southwest at 225 degrees, which is five degrees lower, and the nearest cardinal direction is West. Read this as 5 degrees West-Southwest. If your orientation had been 220 degrees, you would read it as 5 degrees South-Southwest.

Why do they call it Compass Rose?

the-origins-of-the-compass-rose. The compass rose has appeared on charts and maps since the 1300's when the portolan charts first made their appearance. The term "rose" comes from the figure's compass points resembling the petals of the well-known flower. ... Naming them all off perfectly was known as "boxing the compass".

How do you read a Windrose?

Wind roses are set up in a circle, just like a compass. When looking at one, the top represents north, the right represents east, the left west, and the bottom south. As a "spoke" extends along one of these directions, that indicates the wind was blowing from that direction, not toward it.

Is east right or left?

Navigation. By convention, the right hand side of a map is east. This convention has developed from the use of a compass, which places north at the top.

Is an intermediate direction?

The cardinal directions are north (N), south (S), east (E), and west (W). The intermediate directions are northeast (NE), southeast (SE), southwest (SW), and northwest (NW).

Is north 0 degrees on a compass?

Compasses have four cardinal points: north (N), east (E), south (S), and west (W). Some compasses also display 360 marks called degrees that can be used instead of or in addition to the needle which always points north. North indicates 0° (0 degrees). 90 degrees is East, south is 180°, and west is 270°.

What direction is 135 degrees?

Southeast If 0 degrees is North and 90 degrees is East, then 45 degrees is Northeast. This applies for every adjacent pair of directions, so the midpoint between East (90) and South (180) is Southeast at 135 degrees.
