Thunderstorms Day 1- Brittany

Howdy there pop and grandmommy! How ya'll doing out there in Tennessee? I'm alright out hur it just rains a lot, it ain't nothing like home! We're suppose to get a big ole storm coming our way. The weather forecaster's say that it's a huge thunderstorm that's going to be about 57 mph. Can you believe that pop? Remember when I was living out there and we were in the fields picking corn and that big ole tornado was coming straight for us? That wind was very fast and I'm scared that this storm gonna be just like it! These darn storms average bout 15 miles in diameter, what if that area is where my home is, grandmommy I need you hur to take care of me. The guy on the TV says that thunderstorms can last about 30 minutes, what if my power goes out and I have to sit in the dark all by myself? The only thing that makes me feel a little better is that we are learning bout thunderstorms in my science class right now which means at least I can understand what’s going on! Mrs. Muhlenforth says that thunderstorms need moisture, unstable air, and a lift of air so that the storm can be created. She's also teaching us about how it forms. It’s pretty complicated but once ya get a hang of it your in great condition. See, first the sun heats up the surface of earth which warms up the air above the surface. This is where the lift of air comes in, so pay close attention! Then that air rises up to cliffs or mountains creating something called rising motion, then the rising motion transfers the heat to the atmosphere. Up high, high in the atmosphere the water vapor cools the air releasing the warmth and it condenses into a cloud. Now this is where I got confused and had to ask her to help me out. After it makes a cloud, the cloud reaches freezing temperatures causing the vapor to turn into either ice or rain. Both ice and rain have what they call electrical charges and when the charges build up a bolt of lightning is created and booms through the sky! The lighting causes a sound wave and ta da thunder! Aren't ya glad I'm paying attention up hur? I sure am I understand lots of stuff now. Now I'm just waiting for this storm so that I can see the sky light up with bolts of quick disappearing lighting! Oh grandmommy I have to tell you something very important! If pop is out in the field and you happen to look out the window and see some lighting and here some thunder count the seconds between each bolt of lighting and each sound of thunder then divide that by 5 and you will be able to figure out how many miles away the storm is! Make sure you do that cause I don’t want pop out there in that scary weather! Aren't ya glad I'm taking this class, it's really informative! I hope to see ya soon grandmommy and pop cause I miss ya lots! No worries I'll be sure to keep ya’ll updated! Love ya'll be safe! Brittany
