Now investigate how rotation affects the path of your pencil line. Again, begin with the cards in the
"cross" position and your pencil point at X. As you slowly pull the lower left tab of the loose card (B)
towards you, slowly move your pencil point away from you along the cut-edge while drawing its path on
(B). The loose card is rotating counterclockwise as you do this. The line you drew is - ANSWER-Curved
On the Figure 3 weather map segment, consider an air parcel at rest at Point A. An initial horizontal
pressure gradient force ________ acting on the parcel. - ANSWER-Is
Solid lines on the 500-mb map join locations where the 500-mb pressure level is at the same altitude.
These lines, called contours of height, are drawn here at intervals of 60 m. The coded height values on
the map are in tens of meters. On the map, contour values are labeled in whole meters. The highest
reported 500-mb height at any individual station on the Figure 2 map was ________ m. - ANSWER-5910
On the Figure 2 map, the lowest height reported at an individual station for a pressure reading of 500-
mb was ________ m. - ANSWER-5510
The 500-mb map and other constant-pressure upper-air maps are actually topographic maps that give
form or shape to imaginary surfaces on which the air pressure is everywhere the same. That is, the
contour pattern reveals the "hills" and "valleys" of the constant-pressure surface. The contour pattern of
the Figure 2 map indicates that, in general, the 500-mb surface (the surface where the air pressure is
everywhere 500 mb) is at a ________ altitude in southern Canada than in the southern U.S. - ANSWER-
Lower
Contour lines on constant-pressure upper-air maps separate regions that have higher altitudes from
those areas that have lower altitudes than the value of that contour line. In Figure 2, the area to the
south of the 5880-m contour across the Southwest U.S. is where 500-mb altitudes are among the
________ on the map. Conversely, on the same map, the area north of the 5520-m contour line in
northern Maine and eastern Canada is a region where 500-mb altitudes are the lowest. - ANSWER-
Highest
,The wave pattern of most of the contour lines on the Figure 2 map consists of topographic ridges and
troughs, that is, elongated crests and depressions, respectively. A ________ appears on the Figure 2
map over the region from the Great Lakes to Mississippi. - ANSWER-Trough
Therefore, the air below the 500-mb region of lowest heights in Figure 2 must be ________ than the air
below the surrounding higher 500-mb surfaces. - ANSWER-Colder
The upper air station model also gives the air temperature at 500 mb. The plotted station data show
that, as latitude increases (i.e. moving poleward), the general decline of 500-mb temperatures are
accompanied by a(n) ________ in the altitude of the 500-mb surface. - ANSWER-Decreases
Suppose that at 12Z 27 OCT 2016 you board an airplane and fly non-stop directly from Tucson, the
southern-most station in Arizona, to Caribou, the northern-most station in Maine. En route, the plane
cruises along the 500-mb surface. Flying from Tucson to Caribou, the aircraft's actual cruising altitude
________. - ANSWER-Decreases
At the same time, the air temperature outside the aircraft ________. - ANSWER-Falls
A relationship exists between the orientation of height contours and wind direction on 500-mb maps,
especially at higher wind speeds. As seen in Figure 2 across the Washington State to Idaho area of the
U.S., wind directions are generally ________ to nearby height contour lines. This is because the frictional
forces acting on moving air at and near Earth's surface diminish rapidly with height and are essentially
absent in determining middle and upper atmosphere motions. - ANSWER-Parallel
The overall circulation pattern of surface winds about the extended low-pressure center from South
Dakota to northern Texas as seen from above was generally ________. This pattern was a result of the
combination of forces including friction at Earth's surface. - ANSWER-Counterclockwise and inward
The highest surface wind speeds at map time were along the region of strongest horizontal pressure
gradient across the upper Plains States. The wind speed at Fargo on the North Dakota-Minnesota
border, and Des Moines in central Iowa, was about ________ knots. - ANSWER-15
Wind directions at stations near isobars were generally oriented ________ to their nearby isobars.
These wind patterns were a result of the combination of horizontal forces acting on air near the surface,
including the horizontal pressure gradient, Coriolis, and friction forces. - ANSWER-At an angle
,Recalling that the heights plotted at individual stations on 500-mb maps are in tens of meters (place a 0
to the right of the three plotted digits), the coded height at Little Rock ("585") indicated 500 mb
occurred at ________ meters above sea level. - ANSWER-5850
On the 500-mb map, the plotted report for Little Rock, in central Arkansas, shows that, at the 500-mb
pressure level over the station, the temperature was ________ °C. - ANSWER--12
The wind at Little Rock was generally from the west-southwest at about________ knots. [Note: When
winds of 50 knots or greater are reported, a pennant is used on the station's wind shaft for a 50-kt
increment along with the appropriate number of long and short "feathers."] - ANSWER-10
Consider the following stations located on the 500-mb map: Albuquerque in north-central New Mexico,
Pittsburgh in western Pennsylvania, Jackson in central Mississippi, and Medford in southwest Oregon.
Examining those stations' data shows this reporting station data are from ________. Current
rawinsonde reports of upper air data can be found from the Upper Air section, "Upper Air Data - Text"
on the RealTime Weather Portal. - ANSWER-Medford, OR
Comparing the wind speeds in a general west-east band across the middle of the country for the 500-mb
level with the surface winds at those same locations at 00Z 26 OCT 2016, shows that, as altitude in the
atmosphere increases, wind speeds generally ________. This relationship results in part from the
absence of friction in the middle and upper atmosphere. - ANSWER-Increase
The 500-mb map also shows that, where contour lines are relatively close, such as across the
northeastern U.S., wind speeds are relatively ________ compared to where contour lines are more
widely spaced. This principle corresponds to the similar relationship between the spacing of isobars and
wind speeds on surface maps. - ANSWER-High
At upper levels, the wind directions are also related to the contours. That is, especially where winds are
relatively fast, the winds are generally ________. - ANSWER-Parallel to the contours
Using the 500-mb station values as well as the contour pattern, compare the reported station heights at
Caribou, in northern Maine; Wallops Island, Virginia on the Chesapeake Bay; and Miami, in southern
Florida. The 500-mb height was lowest over ________. - ANSWER-Caribou
, Also compare the temperatures for Caribou, Wallops Island, and Miami. (Wallops' plot is obscured but
was reported as -16.3 °C.) As you recall from Investigation 5B, the relation of column temperatures to
heights of pressure surfaces was examined using conceptual "pressure blocks." The 500-mb
temperature, reflective of the temperature of the column beneath that level, was lowest at ________. -
ANSWER-Caribou
The lowest 500-mb heights are generally associated with the ________ latitude stations. These upper air
features result from cooler temperatures in the air column between 500 mb and the surface. - ANSWER-
Highest
On the same map, there is evidence of a broad ________ across the region from Montana to New
Mexico. - ANSWER-Ridge
The contour pattern of the 500-mb map has ________. - ANSWER-generally straight west-east flow
across the central U.S.
Planetary-scale air circulation sets the stage for smaller-scale weather systems.
Questions 1 - 4 deal with the idealized circulation patterns of Figure 9.2 that shows in step-wise fashion
how surface winds and pressure patterns would develop on an idealized smooth solid Earth. It shows in
panel A that on the sunlit side of such a non-rotating Earth, surface winds in the Northern Hemisphere
would always blow from the north. This occurs because cold, dense air at polar locations displaces
warm, less dense air at lower pressure encircling the Earth in the tropics. In other words, a ______ is
acting directly from high latitudes towards low latitudes. - ANSWER-
Panel B shows that once the Earth begins to rotate, air moving southward from the North Pole turns
westward well before reaching the equator. This is because rotation of the Earth produces the ______
that acts to the right of the direction of air motion in the Northern Hemisphere. - ANSWER-
Panels C and D show that with continued rotation of an idealized Earth at the current rate of the real
Earth, surface winds eventually assume a three-zone pattern in each hemisphere separated by
alternating belts of high and low air pressure. At middle latitudes (30 to 60 degrees) of the Northern
Hemisphere, surface winds blow from the - ANSWER-
