# Wind Analysis: Overview

The wind analysis evaluates historical wind data (wind speed and direction) at various altitudes and at one or more locations.

It generates summarized monthly evaluations. Annual evaluations are also provided based on the aggregation of the monthly evaluations.

During the creation of the analysis, you can choose whether to perform it as a high-level analysis (evaluation of a specific time of day) or as a detailed analysis (evaluation of all times of day at once). To gain a first impression of the results you can expect, a set of example results is provided within the analysis type selection wizard.

<details>

<summary>Benefits</summary>

* Get an overview on the prevailing wind conditions
* Grouping of intensities (5 classes) and directions (16)
* Comprehensive assessment of wind conditions at highest quality
* Detailed insights into wind strength and directions of a single location
* Visualization of day and night effects

</details>

## High level

The high-level analysis is used to evaluate wind speed and direction at a specific time of day (either day, night, day & night, or custom).

#### Creation

{% hint style="success" %}
Analysis at different altitudes simultaneously (10m (33ft), 152m (500ft), and 305m (1000ft)).
{% endhint %}

{% hint style="success" %}
Analysis at multiple locations simultaneously.
{% endhint %}

{% hint style="success" %}
Analysis of individual time frames and day times.
{% endhint %}

#### Use cases

<details>

<summary>Use cases</summary>

* Useful if a flight mission is already scheduled for a specific time of day/time and only needs to be verified
* For a quick analysis of a specific time of day (High level only analyzes the specified period and is therefore completed faster than the detailed analysis)
* For planning wind speed and direction, if the flight date is outside the one-week evaluation range of NOVA

</details>

## Detailed

The detailed analysis is used to evaluate wind speed and direction for day, night, and day & night simultaneously.

{% hint style="success" %}
Analysis of individual time frames and day times.
{% endhint %}

#### Use cases

<details>

<summary>Use cases</summary>

* Useful if the flight time still needs to be chosen, as it offers an evaluation of all possible times at once
* Likely faster than the high-level analysis if multiple day times need to be analyzed
* For planning wind speed and direction, if the flight date is outside the one-week evaluation range of NOVA
