Base your answers to questions 1 on the photographs below and on your knowledge of Earth science. One photograph shows a digital device that recorded several weather variables. The second photograph shows two weather instruments, labeled A and B.
Based on the outside air temperature and relative humidity shown on the digital device, what is the approximate dewpoint for the time shown on the device?*
The station model below shows several weather variables recorded at a particular location.
What was the most likely dewpoint at this location?*
What is the dewpoint when the dry-bulb temperature is 8°C and the wet-bulb temperature is 2°C?*
Base your answers to questions 4 on the weather map below and on your knowledge of Earth science. On the weather map, the location of the center of a high-pressure system (H) and a front are shown. Isobar values are labeled in millibars (mb). Weather station models represent the weather conditions at Atlanta, Georgia, and Tampa, Florida.
Describe one piece of evidence shown on the map that indicates that Tampa, Florida, has a high probability of precipitation. [1]*
Base your answers to questions 5 on the diagram below and on your knowledge of Earth science. The diagram represents a weather balloon as it rises from Earth’s surface to 1000 meters (m). The air temperature and wet-bulb temperature values in degrees Celsius (°C) and the air pressure values in millibars (mb) are given for three altitudes.
Determine the dewpoint and the relative humidity of the air at Earth’s surface. [1]
Dewpoint: ______________°C Relative humidity: ________%*
