Chapter 5: Storm Chasing (MetEd, Into the Storm) Chapter 6: Lightning, Thunder, Tornados Chapter 7: Tropical Storms & Hurricanes Mr. Hartwell UNIT B – SEVERE STORMS & STORM CHASING

A safety course in chasing, spotting, and reporting Severe Weather CHAPTER 5: STORM CHASING & SPOTTING

Inherent dangers Thousands of people chase severe weather in the United States Thrill seekers side by side with professionals Beware: Serious injury or death may occur

BASICS OF STORM SPOTTING Who can be a spotter? What spotters look for SKYWARN spotter training Types & stages of thunderstorms Severe weather mechanics Thunderstorms, tornados, hurricanes Safety when chasing & spotting

Serious injury can occur Course does not certify you to be a chaser Course does raise awareness of threats and safety measures Course does certify you to be a NWS storm spotter & reporter Any trained person may be a storm spotter

Spotters look for: Tornados Funnel Clouds Wall & shelf clouds Rain free cloud base Convective supercells Downbursts Lightning, hail, gusty wind, flooding, snow Any weather-related hazard!

This course covers the basics of being a SKYWARN Spotter. Goals: Provide baseline training for all spotters in communication and spotter report criteria Safety considerations for all hazards SKYWARN SPOTTER TRAINING

SKYWARN MODULES Module 1: Role of the SKYWARN Spotter Module 2: SKYWARN Spotter Convective Basics

AT THE CONCLUSION OF SPOTTER TRAINING… Pass the 2 module quizzes Earn & print your certificate of completion Register with the NWS (National Weather Service) office in Binghamton Begin spotting & reporting severe weather!

SKYWARN SPOTTER TRAINING GOAL #1: ENROLL IN SPOTTER TRAINING SCHOOL GOAL #2: PASS MODULE 1 – EARN CERTIFICATE GOAL #3: PASS MODULE 2 – EARN CERTIFICATE GOAL #4: REGISTER WITH THE NWS

Basics of Storm Chasing Types of Thunderstorms Single cell Multicell cluster Multicell line Supercell Rear flank Classic Front flank

SINGLE CELL

MULTI CELL CLUSTER

LINE (SQUALL LINE)

MULTICELL LINE

SUPERCELL STORM

Types of Supercells Rear flank Classic Front flank

REAR FLANK SUPERCELLS Low precipitation (LP) Updrafts in “rear” of storm (trailing) Hail is difficult to discern No “bow echo” visible on radar

CLASSIC SUPERCELLS Large, flat updraft cloud bases Heavy precipitation Large hail Potential for strong, long-lived tornados

FRONT FLANK SUPERCELLS High precipitation (HP) Updraft in front of storm (leading edge) Wall cloud formation likely Tornados wrapped in rain Extremely heavy precipitation and flash flooding

FRONT FLANK SUPERCELLS

WALL CLOUD IN HP SUPERCELLS

Dangers of Supercell Chasing 1.Bad driving 2.Gusty winds / Tornado death 3.Hail 4.Heavy rain / Hydroplaning 5.Lightning strike 6.Core punching 7.No escape plan

CORE PUNCHING NOT RECOMMENDED! Even for the most advanced and experienced storm chaser

CORE PUNCHING NOT RECOMMENDED! Rushing through rain/hail to catch up to a storm moving away from you The only way to glimpse the tornado, or you’ve missed it Highly dangerous Poor visibility Heavy rain/hail Tornados may be masked in rain, or just beyond the rain/hail boundary IT MAY BE TOO LATE -- DEATH MAY OCCUR!

CORE PUNCHING

Notes on Safety #1 most dangerous place: highways Pull all the way off the road Ensure you have plenty of fuel (1/2 tank rule)

BEGIN SPOTTING & REPORTING SEVERE WEATHER! Pass the 2 module quizzes (Sept./Nov.) Earn & print your certificates of completion Register with the NWS (National Weather Service) office in Binghamton Be safe!
