Question
SOEE1401 Weather Assessed Coursework (30%) Electronic submissions only Submit through Gradescope on Minerva in 'Submit My Work' The coursework will account for 30% of your total module mark. Allocation of marks for each part are indicated below. The coursework involves charts that you will analyse and you will be asked to make a forecast for Leeming, which is near Leeds. The tasks are broken down into three parts: 1) marking isobars, fronts and weather on the chart provided, 2) making a forecast based on charts, and 3) predicting the overnight minimum temperature. Charts provided: • • • • . 12 UTC on Tue 11th April 2017 Synoptic Analysis chart (A). Graph for calculating surface winds and overnight temperature adjustment table (B). 14 UTC on Tue 11th April 2017 Station Observation chart (C). 09, 12 and 15 UTC on 11th April 2017 visible satellite images (S1, S2 and S3) and 09, 12 and 15 UTC rainfall radar charts (R1, R2 and R3). Forecast charts at 00 and 12 UTC on Wednesday 12th and Thursday 13th April 2017 (F1, F2, F3 and F4), respectively. Analysis 1. Plot isobars at appropriate 4 hPa intervals on the Station Observation chart (C) using values of 1008, 1012, 1016, 1020, 1024, and 1028 hPa. Mark on the position of any fronts and circle where any significant weather is occurring at the observation time. Upload your annotated chart C to Gradescope. Forecast [Worth 15%] 2. In no more than 450 words*, use charts F1 to F4 to describe how the synoptic situation evolves over the UK during the next two days up to 12 UTC Thursday 13th April. The way to approach this question is to imagine your description will be read by a meteorologist who does not have access to the charts. It is your task to provide the meteorologist with a very clear understanding of the synoptic situation on F1 and then how this situation evolves through to F4. At least for the F1, you should describe, in order, pressure systems (highs/lows), airmasses, any fronts, precipitation, weather, temperatures, dewpoints, clouds, and winds. Then highlight the main changes from F1 to F4 as appropriate. You have limited wordcount so you will have to be very concise and clear. You may have to be selective about what you highlight in terms of changes from F1 to F4. [Worth 60%] (*Note: this question has a wordcount maximum of 450 words. I will read and mark only material up to and including 450 words.) Page 1 of 3 TURN OVER 3. Estimate the overnight minimum temperature midnight on the 11th April at the Leeming observation station (marked L on chart C, and also shown in the corner), using the formula: Tmin=0.5*(Tmax+Tdmax ) - K where Tmax and Tdmax are the temperature and dew point temperatures at the maximum temperature earlier that day (usually around 14 UTC) and K is an adjustment that depends on the wind speed and cloudiness. The values for K are given by the table on page B. You will be required to fill in the values for the table below. The same values will be entered into Gradescope for an equivalent table.

Once Gradescope loads, click on the 1401 Assessed Coursework 30% link and enter your answers for the coursework. The Gradescope link will be open approximately a week before the deadline and you can test submitting answers to become familiar with the system. You can submit updated final answers up until the due date. Late submissions will be subject to late penalties according to the School's COPA. No late submissions will be accepted once submissions are graded and returned. The assessment will be marked in terms of the following criteria: 1. The correct and accurate plotting of isobars, fronts, and weather, including correct and appropriate labelling with units where appropriate. 2. The forecast will be marked based on adhering to the instructions in the brief, accuracy of the predictions, evidence of understanding, clarity of the description of the forecast, and conciseness of the statements, including correct terminology and units. 3. The overnight temperature including all the values in the table 3a) to 3i) will be graded on the accuracy of the values provided in the units requested, where appropriate. Finally, please note that the coursework must be all your own work and academic integrity of submissions will be checked. Page 3 of 3 END
