How far, in miles, can lightning travel from the storm causing it?
Correct Answer
C. 10
Explanation
Lightning can travel up to 10 miles from the storm causing it. This distance is known as the "flash range" and is the maximum distance at which lightning can strike the ground. Beyond this range, the electrical charge dissipates and the lightning is no longer a threat. Therefore, the correct answer is 10.
2.
How much rain, on a 30 year average basis, falls in Tucson during the Monsoon, in inches??

3.
Which best describes a dry microburst?
Correct Answer
C. Rain falls into a dry layer of air. This rain evaporates in the dry air, which cools the air. Since cool air is heavy and dense, it rushes down to the ground and spreads in all directions.
Explanation
A dry microburst occurs when rain falls into a dry layer of air. The rain evaporates in the dry air, causing the air to cool. As cool air is heavier and denser than warm air, it rapidly rushes down to the ground and spreads in all directions. This downward rush of cool air, combined with the spreading of rain, leads to the collapse of the thunderstorm. The lack of upper-level steering flow and the absence of tilt in the storm contribute to the direct alignment of inflow and outflow, further weakening the storm.
4.
Which best describes a wet microburst?
Correct Answer
C. The thunderstorm collapses quickly because there is little upper-level steering flow, resulting in the storm no longer being tilted. This lack of "tilt" makes the inflow and outflow (wind entering the storm and rain leaving the storm) directly on top of one another, thus killing the storm. The wind and rain then rush down to the ground and spread in all directions.
Explanation
A wet microburst is described as a thunderstorm that collapses quickly due to the lack of upper-level steering flow, causing the storm to no longer be tilted. This lack of "tilt" leads to the inflow and outflow of wind and rain being directly on top of one another, which ultimately kills the storm. As a result, the wind and rain rush down to the ground and spread in all directions.
5.
What is El Niño? Choose the best description.
Correct Answer
C. Warmer than normal water gathering in the equatorial Pacific which causes above normal rainfall in the southwestern US during the winter and below normal rainfall in the Monsoon. It typically rears its head during the winter months. Fishermen off the coast of South America often must move northward to make large catches, following the cooler, more nutrient rich waters.
Explanation
El Niño refers to the phenomenon of warmer than normal water gathering in the equatorial Pacific, resulting in above normal rainfall in the southwestern US during winter and below normal rainfall in the Monsoon. This phenomenon typically occurs during the winter months. As a result, fishermen off the coast of South America often have to move northward to find cooler and more nutrient-rich waters, where they can make larger catches.
6.
What is La Niña? Choose the most complete answer.
Correct Answer
C. The trade winds begin blowing more strongly from east to west from South America into the Pacific, upwelling cool water. This results in cooler-than-normal sea surface temperatures in the equatorial Pacific. The Monsoon is often enhanced by La Niña.
Explanation
La Niña is a weather phenomenon characterized by the strengthening of trade winds blowing from east to west across the equatorial Pacific Ocean. These winds cause the upwelling of cool water, resulting in cooler-than-normal sea surface temperatures in the region. This cooling effect can have various impacts on global weather patterns, including the monsoon. During La Niña, the monsoon is often enhanced, leading to increased rainfall in certain regions.
7.
Which of the following is NOT a source for moisture during our Monsoon?
Correct Answer
E. Gulf of Alaska
Explanation
The Gulf of Alaska is not a source for moisture during our Monsoon. Monsoons are characterized by the seasonal reversal of winds, which bring moist air from oceans to land, resulting in heavy rainfall. The Gulf of Alaska is located in the northeastern Pacific Ocean and does not contribute significantly to the monsoon system. The other options listed, such as the Gulf of Mexico, Pacific, Atlantic, and Gulf of California/Sea of Cortez, are all potential sources of moisture during the monsoon season.

14.
From the bottom to the top of a rainbow, the colors are _________ to __________ and in the secondary rainbow from ________ to __________
Correct Answer
D. Violet to red; red to violet
Explanation
The colors of the primary rainbow (or bottom rainbow) is from the violet to the red, but because a secondary rainbow is formed because of two reflections within a raindrop, it switches which color is on top for the second (or top) rainbow, so the colors are red to violet (and will appear more faint)
15.
Where is the ONLY safe place to be in a thunderstorm?
Correct Answer
D. Inside a building (with four walls and a roof)
Explanation
Lightning can spread out in all directions, and just because you might be under a roof, lightning can actually travel sideways and hit you. Trees are tall and can attract lightning so NEVER stand under one during an electrical storm. A building or car are the only safe places during a thunderstorm. If you hear thunder, you are too close and must seek shelter. A car is also a safe place.

What do you do if you are driving and get caught in a dust storm while driving on the Freeway?
Correct Answer
A. Pull over and take your foot off the break, turn off your lights, and make yourself invisible
Explanation
Dust storms can drop visibilities quickly. It is recomended by DPS to pull far off the side of the road, turn off your lights and take your foot off your break. If your lights are on, people could try and "follow you" and run into your parked car.

Choose the most deadly, on average in the United States, of the following
Correct Answer
A. Flooding
Explanation
Flooding is the most deadly, on average in the United States, among the given options. Flooding can cause significant damage to infrastructure, homes, and lives. It can lead to swift and powerful currents, submerging vehicles and causing drownings. Additionally, flooding can result in the destruction of buildings, contamination of water sources, and the spread of waterborne diseases. Flash floods, in particular, can occur with little warning, making them especially dangerous. The combination of these factors makes flooding the most deadly natural disaster in the United States.
