What is at high latitudes.

In the Northern Hemisphere, which of the following (Summer Solstice, Winter Solstice, Vernal Equinox, and Autumnal Equinox) has the fewest hours of daylight?
What is Winter Solstice

The north-facing side of a hill in a mountain region in the US tends to ______________ than the south-facing side.
What is (receive less sunlight, different variety of trees, better for ski run, snow on the ground longer)

At 40°F, the atmosphere is saturated with water vapor. If the air temperature increases to 60°F, with no addition or removal of water vapor, one may conclude that the dew point is about
What is 40°F

In the Northern Hemisphere, why are summers warmer than winters, even though the earth is actually closer to the sun in January?
What is there is more insolation in summer (longer days, larger sun angles).
200
The days are nights are equal lengths at the poles, at noon the sun is overhead at the equator, the earth is not tilted towards or away from the sun. All of this happens on what day?
What is Equinox.

Hypothermia is most common in
What is cold, wet weather

At any given time, ____________ of the earth is illuminated by the sun
What is 1/2

What is the BEST indicator of the actual amount of water vapor in the air?
What is Dew Point Temperature

Why is the largest annual range of temperatures normally observed over continents away from large bodies of water?
What is continents are generally less humid as compared to oceans, thus their temperature ranges tend to be larger than over oceans. The larger heat capacity of water as compared to land further moderates the temperature ranges.

In clear weather, the air next to the ground is usually ____ than the air above during the night and ____ than the air above during the day.
What is colder, warmer

In July, at middle latitudes in the Northern Hemisphere, the day is ____ long and is ____ with each passing day.
What is more than 12 hours, getting shorter
300
Maximum daily temperatures under hazy skies are typically ___________ than those under clear skies.
What is greater than

As the air temperature increases, with no addition of water vapor to the air, the relative humidity will
What is decrease

Why are specific humidity and mixing ratio more commonly used in representing atmospheric moisture than absolute humidity? What is the only way to change the specific humidity or mixing ratio of an air parcel?
What is a rising or descending parcel of air will experience a change in its volume because of the changes in surrounding air pressure. Consequently, when a volume of air fluctuates, the absolute humidity changes—even though the air’s vapor content has remained constant. For this reason, the absolute humidity is not commonly used in atmospheric studies. Specific humidity and mixing ration, on the other hand, do not depend on the volume of the air. Specific humidity and mixing ratio can only change if water vapor is added or taken away from an air parcel.

Water heats up ____________ and cools off __________ than land.
What is more slowly, and more slowly
400
If water vapor comprises 3.5 percent of an air parcel whose total pressure is 1000mb, the water vapor pressure would be
What is 35mb
400
Explain why the air on a hot humid day is less dense than on a hot dry day.
What is water vapor molecules weigh less than the other molecules that make up most of the air (N2 and O2). On a hot humid day the percentage of lighter water vapor molecules is greater than on a hot dry day, thus the air on a hot humid day is lighter and less dense than on a hot dry day.

Briefly describe how the following thermometers measure air temperature: (a) liquid-in-glass (b) bimetallic (c) electrical (d) radiometer
What is Liquid-in-glass thermometers have a glass bulb attached to a sealed, graduated tube about 25 cm (10 in.) long. A very small opening, or bore, extends from the bulb to the end of the tube. A liquid in the bulb (usually mercury or alcohol) expands or contracts, rising up or down the tube, as the temperature rises or falls, respectively. A bimetallic thermometer measures temperature by measuring the difference in expansion between to different types of metal (usually brass and iron). Temperature changes cause different amounts of expansion between the two metals, causing the strip to bend. Electrical thermometers are highly accurate instruments that measure the electrical resistance of a wire, which depends on temperature. A radiometer measures the amount of infrared radiation, which is related to temperature.
