1What is the formula for calculating sensible heat (Qₕ)?
2During a clear day, what is the relationship between incoming solar radiation (K↓) and outgoing solar radiation (K↑) at 1200?
3Which of the following statements accurately describe the effect of cloud cover on radiation balance components based on the provided data?
4Calculate the change in temperature (ΔT) of 1 kg of still water if 5.2 x 10⁴ J of energy is supplied, given the specific heat of water is 4.18 x 10³ J kg⁻¹ K⁻¹.
5In mid-latitudes of the Northern Hemisphere, what is the significance of a southerly aspect for a topographic slope in relation to solar radiation?
6Explain the concept of albedo and provide examples of surfaces with high and low albedo, referencing their impact on radiation absorption.
7Compare the net radiation (Q*) values between the clear day and cloudy day tables at 1200. What does this difference suggest about the impact of clouds on net energy gain at the surface during midday?
8Calculate the sensible heat required to raise 4 kg of dry peat soil from 20°C to 35°C, given its specific heat is 1.9 x 10³ J kg⁻¹ K⁻¹.
9How does the presence of bare rock and light forested vegetation between glaciers at Mount Rainier likely affect the local surface temperature and melt rate compared to the glacier surface?
10Consider the phenomenon where melting glaciers reveal more sediment and bare rock. How does this process create a positive feedback loop for the glacier's melt rate?
