Himmler et al. were believers in the World Ice Theory, championed by Scultetus in the SS. His popularity oscilated but at various points they were trying to use his ideas to predict the weather.
The basic idea of the World Ice Theory is that a star filled with water crashed into our sun, exploding and spewing out water, hydrogen and such, which froze and coalesced into planets. Many of these planets impacted the Earth, leading to different types of rock formations (because rocks are made of ice, explosions changed the soil composition like during periods of greater volcanic activity or or or... subtheories abounded.) Noah's flood was caused by such an ice planet turning into hail in the atmosphere.
Tangentially, the Nazis also sent a few meteorological and astronomical teams hoping to see the other side of the Earth according to the hollow Earth theory.
