1. Suppose the environmental lapse rate is 7°C per 1000 metres. If the air temperature at the surface is 17°C, what would be the air temperature measured by a radiosonde at 4000 metres above the surface?
2. Suppose a parcel of dry air is lifted from the surface to an elevation of 4000 metres. If the temperature inside the air parcel at the surface is 25°C, what would be the temperature of the air inside the parcel at 4000 metres if the rising air parcel remains unsaturated?
3. Consider the temperature of the air at 4000 metres as measured by the radiosonde in (#10). Now consider the temperature of the rising air inside the parcel at 4000 metres in (#11). a) Is the air temperature inside the parcel at 4000 metres warmer or colder than the air surrounding it (as measured by the radiosonde)?
b) In this situation would the atmosphere be considered stable or unstable?
4. Suppose a parcel of unsaturated air is lifted from the surface to an elevation of 3000 metres. If the temperature inside the parcel at the surface is 12°C and the parcel became saturated at an elevation of 2000 metres, what would be the parcel temperature at 3000 metres?
5. After a large snowstorm, the newspaper reports the water equivalent of the precipitation for Brandon, Manitoba to be 23 mm. If we assume all of the precipitation fell as snow, then how many cm of snow did the city receive?
