It was a unique approach to the problem of how terrain impacts storms, examining correlations between radar parameters and elevation. After his project was completed, I expanded the dataset and played around with it,… Continue reading

Delicate Wisps in Equilibrium: How Lonely, Stray Cumulus Clouds Appear in Blue Sky (Weather Explained #1)

Stray cumulus clouds form when clean air, weak heating, and subtle feedbacks align just enough for condensation to appear. These delicate clouds are brief structures born from balance, where sunlight, moisture, and turbulence meet only momentarily before the sky returns to a brilliant blue. Continue reading
