Exam 3: Seasonal and Daily Temperatures

Describe the seasons that you would experience at two widely different locations on Earth. How might seasonal variations affect a region's culture and traditions?

Suppose the temperature at night is going to drop to -5°C, and a fairly stiff wind is predicted. Assuming that cost is not a factor, which of the following methods is probably the best way to protect an orchard against a hard freeze?

Why does the warmest weather in middle latitudes normally occur several weeks after the summer solstice?

Suppose the air temperature is -5°C, the wind is blowing at 55 km/h, and the wind chill temperature is -15.3°C. Which of the following temperatures and wind speeds are equivalent to these conditions?

Suppose the minimum temperature reported in the newspaper is 2°C, but you notice ice crystals (frost) on the grass in the morning. Which of the following describes the most likely reason for this apparent discrepancy?

Referring to the diagram, sunlight energy is added at equal rates to soil and water. Which of the following factors contributes to the different temperatures of the two surfaces?

Consider the scenario in which peas are planted in Ontario on May 1. If the peas need 1200 growing degree-days before they can be picked, and if the mean temperature for each day from May to July is 21°C, in about how many days will the peas be ready to pick? (Assume a base temperature of 4°C).

In the Northern Hemisphere, which of the following days has the fewest hours of daylight?

During which of the following months does Indian summer most likely occur?

Under which of the following conditions do the strongest radiation inversions occur?

Explain why highest summer temperatures usually occur over desert regions as opposed to humid areas with more vegetation.

In which of the following circumstances is a radiation inversion most commonly observed?

Assume that the night will remain clear, calm, and unsaturated, and the predicted minimum temperature is 0°C. Suddenly the wind speed increases and remains gusty throughout the night. What would be the most likely minimum temperature?

In meteorology, which of the following defines "insolation"?

At Lima, Peru (latitude 12°S), on which of the following days is the sun overhead?

At which of the following locations are the days and nights of equal length all year long?
