Question

Surface Station Model (9 points): Plot the following weather data, from Republic Airport in Farmingdale, NY at

19:53 Z (3:53 PM EDT) on 03 May 2001, onto the surface station model below.

Temperature (T) = 82°F

Dew Point Temperature (Td) = 57°F

Wind speed = 10 knots

Wind direction = Northeast or 45°

pressure 1020.3 mb

Sea level

Pressure change = 2.3 mb

Pressure Tendency = SSR

Visibility = 8 miles

Sky Coverage Total = 0/8

Present weather = None

=

o

Pressure Conversion (2 Points): You must show all of your work in the space provided in order to receive full

credit for this problem. Round your final answer so that there is only one digit after the decimal point. Circle

your final answer along with its appropriate unit. Conversion Factor: 1 in.of Hg = 33.86395 millibars

Convert the pressure of 30.07 inches of mercury into millibar's: Decoding a METAR Report (1Point each): Given the following METAR report:

KLGA 170851Z 18010G25KT 1/4SM +RA OVC080 07/07 A2993 RMK P0014

Use the METAR Abbreviations Table to decode the following information from the METAR report above. Be sure

to include the proper unit, if necessary, as a part of your answer. Failure to write down the proper unit, when

necessary, will cause you to get that problem wrong. Write the letters "N/A" if the requested information was not

present in the METAR code. Leaving a question blank will cause you to get that question wrong.

Zulu Time Isotherms (10 Points): On the following map, draw all possible isotherms as you were taught in lab. Use the proper color, proper increment and label your lines. The little black

dots are the exact location of the temperature reading. If you are unable to read the temperature value please ask your instructor for clarification.

سپر Isobars (20 Points): On the following map, decode the pressure values and draw all possible isobars as you were taught in lab. Be sure you use the proper color, proper increment and label your

lines. Then find and label one LOW pressure system and two HIGH pressure systems. There maybe another low in Canada, but this low is weaker and not the main low pressure system on the map.

Make sure you give the high and low pressure areas their proper symbols with its appropriate color. The little black dots under each pressure value mark the exact location of the pressure reading. If

you are unable to read the coded 3-digit pressure value please ask your instructor for clarification. If the pressure value only consists of two numbers then assume the last number is zero.
