scary. this is one of my nightmares that often happened, it's not because i am studying meteorology, or it's because i am too much learning about it and brought until i am fall asleep? heh... anyway, this is really scary, not just they're big, but this is the beginning of tornado wind, from very big, or i can say huge cumullonimbus clouds, that increasing over and over until meet the inversion layer above, so it can't grow up, so they're grow down to below. thank god, this kind of cloud rare happens in our country. this is amazing somehow. i can't imagine how if they're exist over sea and the sailor set the sail below them, oh my god. x_x
