Thunderstorms

Question 1

Ordinary cell thunderstorm

Answer 1

Thunderstorm produced by local convection with the conditionally unstable air mass. It often forms in a region of lower windshear and does not reach the intensity of a severe thunderstorm.

Question 2

What is a macroburst?

Answer 2

A strong downburst greater than 4 km across

Question 3

What happens in the second stage of a single cell thunderstorm

Answer 3

Severe weather is at its maximum

Question 4

What is a multicell thunderstorm?

Answer 4

Under storms that contain a number of cells each in a different stage of development

Question 5

What is a mesocyclone?

Answer 5

Rotating column of air on the southside of the storm

Question 6

What is the third stage of a single cell thunderstorm?

Answer 6

Dissipating stage

Question 7

What is the second stage of a single cell thunderstorm?

Answer 7

Mature stage

Question 8

Where are multicell thunderstorms likely to form?

Answer 8

Region of moderate to strong vertical wind speed shear

Question 9

Outflow boundary

Answer 9

A surface boundary separating cooler, more dense air from warmer less dense air.

Question 10

__ second delay = 1 mile

Answer 10

5

Question 11

A thunderstorm typically begins with ______, ______ air rising in the conditionally _______ environment

Answer 11

Warm, moist, unstable

Question 12

What is lightning?

Answer 12

Able to electricity fired from a thunderstorm

Question 13

Gust front

Answer 13

When Cold downdraft reaches Earth surface it pushes outward in all directions

Question 14

Single ordinary thunderstorm may go through it’s three stages in ___ hour or less

Answer 14

1

Question 15

What three things are needed to form a thunderstorm?

Answer 15

Moist surface air, a conditionally unstable atmosphere, a trigger that forces the air to rise

Question 16

What is a downburst?

Answer 16

A severe localized downdraft that can be experienced beneath a severe thunderstorm

Question 17

What is a mesoscale convective complex?

Answer 17

Or thunderstorms merged together

Question 18

Severe thunderstorms are defined as storms that produce at least one of the following 3 things:

Answer 18

Large hail, surface winds of 50 knots, or a tornado

Question 19

Happens in the third stage of a single cell thunderstorm?

Answer 19

Updraft weekend and storm runs out of energy

Question 20

What is a squall line thunderstorm?

Answer 20

Multi celled thunderstorms that form a line along a front

Question 21

Under storms are ______ storms that form with _______ air

Answer 21

Convective, rising

Question 22

What is a microburst?

Answer 22

A strong localize downdraft less than 4 km wide that occurs beneath thunderstorms

Question 23

How large is the mesocyclone?

Answer 23

5 to 10 km across

Question 24

What happens in the first stage of a single cell thunderstorm?

Answer 24

A towering cumulus develops

Question 25

What is thunder?

Answer 25

Shockwave heard from the lightning

Question 26

How is an outflow boundary formed?

Answer 26

By the horizontal spreading of cool air that originated inside a thunderstorm

Question 27

Straight-line winds

Answer 27

Highwinds behind a strong gust front

Question 28

Where are squall lines likely to form?

Answer 28

Directly along a cold front

Question 29

First stage of a single cell thunderstorm?
