Base your answers to questions 1 on the weather map below. The map shows isobars and seven weather station models. Four of the weather stations are identified by letters A, B, C, and D.
Which weather information shown at station B was measured with an anemometer and weather vane?
*
A weather station model is shown below.
Which information shown on the station model is most closely associated with measurements from an anemometer?
Which weather instrument is used to determine wind direction?
Which weather instrument is most useful in measuring relative humidity?*
Which weather instrument is used to measure air temperatures recorded on a weather map?*
The diagram below shows a weather instrument used to determine relative humidity.
What is the relative humidity?*
Which set of instruments is correctly paired with the weather variables that they measure?*
A psychrometer is used to determine which weather variables?*
Base your answers to questions 9 on the weather map below and on your knowledge of Earth science. The map shows the location of a low-pressure system over New York State during late summer. Isobar values are recorded in millibars. Shading indicates regions receiving precipitation. The air masses are labeled. Eight locations in New York State are indicated.
Identify the weather instrument used to measure air pressure. [1]*
Base your answers to questions 10 on the diagram below, which shows the windward and leeward sides of a mountain range. Arrows show the movement of air over a mountain. Points A and B represent locations at sea level on Earth’s surface.
Identify one weather instrument that could be used to determine the dewpoint of the air at point A. [1]*
Base your answers to questions 11 on the air pressure field map in image provided and on your knowledge of Earth science. The map shows air pressures recorded in millibars (mb) at locations in eastern North America. Four isobars are shown. Points W, X, Y, and Z represent locations on Earth’s surface. Letter L represents the center of a low-pressure system.
Base your answers to questions 12 on the weather map in image provided and on your knowledge of Earth science. The weather map shows atmospheric pressures, recorded in millibars (mb), at locations around a low-pressure center (L) in the eastern United States. Isobars indicate air pressures in the western portion of the mapped area. Point A represents a location on Earth’s surface.
Identify the weather instrument that was used to measure the air pressures recorded on the map. [1]*
Base your answers to questions 13 on the map in image provided and on your knowledge of Earth science. The weather map shows isobars, recorded in millibars (mb).
The table below lists some weather conditions for another location on this map.
On the weather station model in your answer booklet, using the proper format, record the weather conditions listed in the table. [1]
Base your answers to questions 14 on the weather map below and on your knowledge of Earth science. The map shows the location of a low-pressure system over New York State during summer. Isobar values are recorded in millibars. The darker shading indicates areas of precipitation. Some New York State locations are indicated.
Identify the name of the weather instrument used to measure the wind speed at Plattsburgh. [1]*
Base your answers to questions 15 on the map in image provided and on your knowledge of Earth science. The map shows the path of a tornado that moved through a portion of Nebraska on May 22, 2004 between 7:30 p.m. and 9:10 p.m. The path of the tornado along the ground is indicated by the shaded region. The width of the shading indicates the width of destruction on the ground. Numbers on the tornado’s path indicate the Fujita intensity at those locations. The Fujita Intensity Scale (F-Scale), in the left corner of the map, provides information about wind speed and damage at various F-Scale intensities.
Identify the weather instrument usually used to measure wind speed. [1]*
