Question

The purpose of this lab is to introduce some of the available tools used to prepare a weather forecast.

Surface Analysis – http://weather.rap.ucar.edu/surface/sfc_alb.gif

Satellite Imagery- http://www.goes.noaa.gov/

Radar - http://radar.weather.gov/radar.php?rid=box&product=N0R&overlay=11101111&loop=no

Models – http://mag.ncep.noaa.gov/model-guidance-model-area.php (Links to an external site.)

SURFACE ANALYSIS: The surface analysis map shows the current meteorological conditions for the Northeast US. Note the symbols used on the map. These symbols are explained in Appendix B. Once you learn how to read the symbols you can “see” the weather on this map.

SATELLITE IMAGERY: When you look at this page you can see that we have imagery for the Eastern Contiguous United State (East CONUS) along with the Western US., Puerto Rico, Alaska and Hawaii. Note we can see images in the infrared (so we can see the weather at night); the visible (only see those areas during the daylight); and water vapor show geographically where the water is in the atmosphere. Note: When we look at the visible and infrared images the brighter the clouds the higher they are in the atmosphere (which is an indication of lift, convection, and possible instability).

RADAR: Radar shows us precipitation type, intensity, and geography. When you go to this page click on Doppler University and read through the tutorial to gain an understanding of how radar works. MODELS: When you arrive at this site you will see that you can select the geographic location to investigate (select North America) and Model Type (select GFS). This will bring to a page of more selection criteria. Review the page and select precipitation parameters precip_p12. This will again open a new page and select Loop All. A map will appear showing High and Low pressure systems along with precipitation shields. Note along the top of the map you will see the time stamp as the model progresses.

CLOUDS: Clouds are the visible manifestations of the atmospheric physics. Cloud types can tell us about what weather to expect. There is an excellent cloud guide in the back of your text.

Note all of these site where navigated to from the Boston National Weather Service Site: http://www.erh.noaa.gov/er/box/ I suggest you take a good look at his site as it has a vast amount of information.

Now using the four tools noted above (surface analysis, satellites, radar, and models) prepare a weather forecast (Maximum and Minimum Temperature for the day and Precipitation amount and type) for 24 hours AFTER your lab submission date. Explain detailing your forecast and how you used the tools to arrive at your weather prediction. Also within the forty eight hour period before your forecast list the type of clouds you observed and the time of day for your observations.

Explanation / Answer

answer- I have used 4 tools in making this report ( Surface analysis, satellite imagery, radar images and surface analysis which shows cloud and high pressure and low pressure it also shows the movement or shiftting of these high or low pressure belt eastward.)

I have selected Puerto rico site for my weather forcast report. the climate of this region is also controlled by the prevailing trade winds and also local topographic differences . In the visible satellite imagery there is few cloud in the atmosphere may be little shower afternoon.and there is presence of low cloud in night which is showing that night is clear in night. Water vapour satellite imagery of the region is suggesting that the region is high is relative humidity. there is presence of huge water vapour in the atmosphere because of precipitation in the afternoon.

the humidty of the region is about 88%

by the study of surface analysis we have found that in the starting there is presence of high pressure which is replaced by the low pressure system that comes from the caribean island and also came from north west direction from alaska.

the maxium temperature of the day in Puerto rico is 26 degree celcius

and minimum temperauture of the day in Puerto Rico is about 22 degree celcius

the amount of precipitation is about 0.46 to 0.50 inch per day

and I have observed Nimbus cloud in the atmosphere before my observation.
