Answer:
Las Vegas
Explanation:
Out of the four cities on this list, Las Vegas is by far the driest one. This can be seen from the levels of precipitation, which for Las Vegas are only 110 mm annually, which is typical amount for a desert.
Las Vegas is a city located in Nevada, and it is actually the largest city in this state. The city is located in the Mohave Desert, so it has a desert climate. It is actually located near the Death Valley, but its temperatures are slightly milder because its elevation is between 500 and 900 meters above sea level.
The summers are hot, while the winters have mild temperatures, with the nights being colder. The precipitation levels are around 110 mm annually, and most of them come in the winter as light rain, while the very rare ones that occur in the summer are in the form of showers.
The climate of Las Vegas is like this because the area is in a rain shadow because of the mountain ranges on the west of it. The mountains are blocking almost rainfall, which falls on their windward side, while the leeward side and the valleys east of it are very dry.
