Tsunamis are not storm-related events, and a thunderstorm is unlikely to affect the height of a tsunami in any significant way.
During a storm or Thunder Storm or is it the same?
Thunder and lightning
No storm is. However, one phenomenon that occurs during some storms can resemble a tsunami. Large, powerful storms such as hurricanes can drive a mass of water known as a storm surge onto land. This storm surge behaves somewhat like a tsunami.

A tsunami is not a storm. It is a wave created by an earthquake or landslide. A tsunami can strike during any kind of weather.
The Vikings believed that, during a thunder storm, the Norse god of thunder, Thor, was riding in his chariot. Whenever lightning flashed, the Vikings believed that Thor was throwing his hammer, Mjollnir.

You cannot really compare them, because they are completely different types of things. A tsunami has the potential to do far more damage than a thunderstorm can, so on that basis, you could say a tsunami is more powerful.
If you are just talking about a thunderstorm, and not a tornado or hurricane, then it would be strong winds, thunder, lightning, and usually rain. A regular storm includes rain and wind, if nothing else.
Of course you can cook during a thunder storm. Most home construction provides some "grounding" that protects people during lightning strikes. However, I wouldn't cook if I had an electric stove.
