What is the Interwave Analyzer?

Interwave Analyzer is a user-friendly software designed to analyze the dynamics of thermally stratified basins, such as lakes and reservoirs, based on temperature and meteorological data. The software can be used to analyze both field and numerical model data.

What is the difference from Lake Analyzer?

Unlike Lake Analyzer, Interwave Analyzer provides a more detailed analysis related to baroclinic activity. The software is coupled with a numerical model to identify different internal seiche modes that can be excited. It applies spectral analysis to isotherms to identify internal waves, highlighting higher vertical modes and wind-resonant seiches.

It also provides theoretical results from the literature, allowing comparison with modeling and spectral outputs. In addition, it computes general parameters describing stratification and mixing in lakes and reservoirs.

Why was Interwave Analyzer developed?

It was created to combine all techniques used to identify internal waves in thermally stratified lakes using temperature sensors. The main goal is to make internal wave analysis easier and accessible, even for users without advanced background knowledge in fluid dynamics.

What is Interwave Analyzer good for?

It is suitable for analyzing lake temperature data and providing information about the internal dynamics of stratified water bodies.

Which data are required?

Required inputs include time-series of water temperature and meteorological data (wind speed and wind direction).

Are there copyright restrictions?

Interwave Analyzer is distributed under the MIT License, meaning you are free to use and modify it. However, we appreciate that modifications to the main code are reported back to the developers.

How to cite in a publication?

BUENO, Rafael de Carvalho; BLENINGER, Tobias Bernward; LORKE, Andreas. Internal wave analyzer for thermally stratified basins, 2021.

Can I have gaps in my data?

No. Interwave Analyzer does not currently support data gaps. All input data should be preprocessed before running the software. A meteorological data treatment module is planned for version 2.00.0.

The GUI is not displayed. What is happening?

Check the command line window for error messages. Often, the issue is related to the tkinter library not being properly installed or missing required files (such as the icon file).

In the precompiled version, incompatibility with your Windows system version may also cause this issue.

My processing stops during execution. Why?

This may arise from multiple factors. Check the command line for error messages and identify where the execution stopped. Depending on data size, the interface may freeze temporarily while processing.

Does the software clearly state if internal waves were generated?

Yes and no. The software provides spectral analysis, theoretical predictions, modeling results, and internal wave properties. However, it does not display a direct message such as "Internal waves were generated." Interpretation is left to the user, supported by guidance in the user manual.

Do I need Python knowledge to run script mode?

No. No programming knowledge is required. You only need to know how to execute a script in your chosen Python interpreter.
