Caption: Figure 11: (a) 600-300 hPa average layer temperature anomalies (
contour interval 0.02[degrees]C) and (b) the difference in zonal wind anomalies between 600 and 300 hPa levels (
contour interval 0.2 m[s.sup.-1]) during anomalous periods of HREs.
It was designated [E.sub.n] as the value of a point on the contour line near P and [E.sub.ci] as the
contour interval. From the features of the contour map, it is clear that, if P is located between two contour lines, w (x,y) should lie between the values of these two contour lines.
Slopes are measurements that compare the horizontal length (measured from the map's scale) to vertical rise or fall (as determined by the contour lines and
contour interval).
The equipment and procedures used to collect the data are influenced by the scale of the map and the
contour interval that will be used.
* Two-foot
contour interval data allowed archaeologists to identify high potential areas prior to fieldwork and to focus their research with greater precision.
- Verify the
contour interval from the map information.
The
contour interval can be set for truly customized contours or the maximum number of
contour intervals.
The
contour interval is 5 cm without zero contours.
Terrain ruggedness indices (Nellemann and Thomson, 1994; Nellemann and Fry, 1995) were calculated for each 1 km2 quadrat on 1:50 000 topographic maps (
contour interval 20 m).
