1. All labs are to be kept in a three hole binder. Turn in the binder when you have finished the Lab.
   
2. Show all work in mathematical problems. No credit given if only answer is provided.

Part I

All are 3 points.

Locate the following features by placing the appropriate letters on the hard copies of the appropriate satellite image (click on Thumbnail to obtain large version for printing).

Image 1

Image 1 1830 UTC 2 March 1999 Hybrid Channels 1, 2, 4

i. A cloud shield. (S)

ii. A cloud line (L)

iii. A cloud street (St)

iv. Snow (Sn)

v. Stratus (St)

vi. An area of texture (indicating either cumuliform tops or mutlilayered cloud decks) (T)

Image 2 2000 UTC 22 February 2000 Hybrid Channels 1, 2, 4

vii. Stratocumulus (closed-cellular pattern) (SC)

viii.Cumulus (open-cellular pattern (CU)

ix. Cloud Band (B)

Image 3 1930 UTC 25 November 1998 Hybrid Channels 1, 2, 4

x. Cirrostratus (Cs)

xi. A subsynoptic (large mesoscale) area of cumulonimbus anvils (CBA)

xii. Mountain Wave clouds (MW)

xiii. Higher clouds casting shadows on lower clouds (Shadow)

xiv. Incipient Frontal Wave Cyclone (IFW)

xv.Altostratus (As)

xv. Area where image suggests that upper tropospheric flow is NOT in phase with mid tropospheric flow (NIP)

xvi. An area of enhanced cumulus (EC)

xvii. Cirrus (Ci)

Part II

The visible, enhanced infrared and water vapor GOES-10 satellite images for approximately 1200 UTC 18 February 2003 are provided below.

Image A: Visible

Image B: 16 km Enhanced IR

Image C: Water Vapor

Image D: 28 km Enhanced IR

1. On the blank map provided, sketch the upper tropospheric flow (streamlines) for the entire north Pacific (use Images B and D primarily for this).

2. To the best of your ability, on a second blank map, do a frontal analysis for the north Pacific (use Images A, B and D for this).

3. Note on the `infrared image (conventional notation):

1. Two long wave trough axes (black)
2. Two long wave ridge axes (blue)
3. A short wave trough axis. (purple)
4. a sharp (green) and a broad (red) ridge axis (could be the same one/s you used in B. above).

4. Discuss why "sharp ridgelines" have little or no cirrus cloudiness past the ridgeline where as "broad ridgelines" often do.

5. Identify and discuss the evidence that suggests which of the two weather systems in the north Pacific has the most significant "moisture tap".

6. Attempt frontal analyses for Images 2 and 3 in Part 1 above.
