Streamline Analysis

Pre-Lab: Definitions & Types of Streamlines ยป Knowledge Check

Before starting the streamlining process, let's check for understanding and ability to identify the aforementioned patterns and features.

Question 1 of 4

What are the three major features in a streamline analysis? Select all that apply.

The correct answers are a, c and e.

Question 2 of 4

A special streamline that depicts an area of major convergence or divergence is called a/an
asymptote

Asymptotes are used in areas of major convergence or divergence

Question 3 of 4

Very briefly describe the wind speed in the center and immediate vicinity of a singular point.


Winds are nearly zero at the center of an indraft/outdraft or neutral point, and are generally light in immediate vicinity

Question

streamline analysis with areas for labeling

Choose the type of streamline or flow feature that is present at each of the numbered points on the image above.

1.
anticyclonic outdraft
2.
neutral point
3.
anticyclonic outdraft
4.
cyclonic indraft
5.
diffluent asymptote
6.
confluent asymptote
7.
neutral point
8.
diffluent asymptote

The correct answers are highlighted in green above. Note that locations 5 and 8 both show diffluent asymptotes - the flow there is diverging out toward the northeast and southwest, to create a line of convergence that runs through locations 6 and 4.
