Distinguish between Weather Warnings and Watches - Assignment Example

Locate this tornado in terms of date, time and place. Cite your source(s) as necessary. Wednesday, June 17th, 2014, 1:03 PM in Angus, http://globalnews.ca/news/1398812/severe-thunderstorm-watch-issued-for-toronto-southern-ontario/c. Was Earth’s atmosphere predisposed towards severe weather on this day, at this place? Convective Available Potential Energy (CAPE) provides an indication. Review the sounding data available from the online repository to estimate the value of CAPE just prior to the occurrence of the Angus tornado.

Environment Canada had issued tornado warnings for several communities in the area as a line of severe thunderstorms with embedded tornadoes moved into the Lake Simcoe region.i. State types (e.g., hail) of precipitation observed. Cite your source(s) as necessary. On Tuesday at around 5:20 pm, a cold front spawned a number of strong to severe thunderstorms across the southern Ontario. This was said by the environment of Canada in the storm summary early on Wednesday. ii. Classify this precipitation in terms of duration/intensity/area - see 3D diagram below.

Preliminary EF-2 with wind speeds near 180 km/hr., the storm lasted for about 15 minutes. e. Was lightning observed? Cite your source(s) as necessary. i. Suppose lightning was observed in Angus, and that you had a clear line of sight from York University to it. How long would it take for you to hear the thunder corresponding to the Angus lightning? State any assumptions required for this estimation. After the storms, several thousands of homes and businesses I Angus were without power. More than 24 hours, customers in Ontario were still not having electricity.

The thunderstorm went out in the following sequence, at 8:47 a.m., the first severe thunderstorm went out, then 10:54 a.m., 2:25 p.m., 2:37 p.m., 3:03 p.m. - 4:54 p.m. then the tornado warning replaces severe thunderstorm warning.f. With which type of thunderstorm was this tornado associated? Cite your source(s) as necessary. According to Environment Canada, the tornado was associated with a severe thunderstorm. It was accompanied by large hail, wind gusts greater than or equal to 50kts, or tornado.

In other words, it was an Ordinary Cell Thunderstorm.g. Illustrate the tornado itself. For example, share a link to a photograph, video or radar image.i. From your illustration, is it possible to quantify the size of the tornado relative to its associated thunderstorm? http://www.theweathernetwork.com/news/articles/tornado-rips-through-angus-ontario-several-homes-damaged-no-major-injuries-reported/29754/. The tornado is approximated to travel at a wind speed of between 180-220 km/hr. and with limited wind shear.h. Quantify the intensity of the tornado.

Cite your source(s) as necessary. The tornado that was experienced in Angus was an EF2 tornado. i. Illustrate the impact of the tornado. For example, share a link to a photograph or video.http://globalnews.ca/video/1475249/return-home-timing-uncertain-for-tornado-victims-in-angus. Tornadoes are very destructive as from the video link above, it led to the death of several people, for instance, the severe thunderstorm led to four people being hit by lightning at a golf course north of Toronto. 2.

Global News has compiled a list of the most-impactful tornadoes in Ontario.a. Using Google Maps (or similar), locate these tornadoes on a map. If possible, use an encoding scheme to indicate the intensity of the tornado. (You could, for example, use color and/or size to encode intensity.) b. Add the location of the Angus tornado to this compilation. i. Consider Figure 14.24 from your AJJ textbook (Slide 36 of the Thunderstorms and Tornadoes lecture). Is there anything exceptional regarding the occurrence of the event in Angus?

These tornadoes are similar to those in Angus. The most exceptional thing about this two is that the average number of days each year on which thunderstorms are observed throughout North America is similar.ii. Consider Figure 14.25 from your AJJ textbook (Slide 37 of the Thunderstorms and Tornadoes lecture). Is there anything exceptional regarding the occurrence of hail in the event in Angus?There is a similarity between the thunderstorm and tornadoes that were experienced in the Angus. The most exceptional thing about these two tornadoes is that the number of times hails is observed clearly matches that of Angus.iii. Consider Figure 14.

37 from your AJJ textbook (Slide 52 of the Thunderstorms and Tornadoes lecture). Is there anything exceptional regarding the time of the year of the event in Angus?From the diagram in slide 52, there is a slight similarity of the weather patterns to that of Angus on the day the tornado occurred. This shows that the two regions share similar weather patterns and are likely to experience the same magnitude of tornadoes.iv. Consider Figure 6 from your AJJ textbook (Slide 64 of the Thunderstorms and Tornadoes lecture).

Is there anything exceptional regarding lake breezes and the event in Angus?Form the figure in slide, there is a great similarity of events that took place in Angus to the one illustrated in the figure. 3. What makes tornadoes so difficult to observe?The tornadoes are difficult to observe since they originate from the thunderstorm. This is so because detection or observing thunderstorm very difficult and challenging since they take place in a span of the very short time.4. What makes tornadoes so difficult to predict?

Tornadoes are difficult to predict since they appear unexpectedly and without warning maybe for a few seconds, minutes or hours. This is so because they come from the energy released in a thunderstorm. As powerful as they are, tornadoes account for only a tiny fraction of the energy in a thunderstorm.5. How might the intensity and/or frequency of Ontario tornadoes be modified if the planet continues to warm? Before answering, please read this article.The intensity and frequency of Ontario tornadoes can be modified for future prevention of destruction by adjusting the accuracy of weather forecast equipment and building structures.

According to the Fujita scale, tornadoes of 5 are the most destructive. For a tornadoes to occur, the wind speed must range from 60 to over 500km/hr. from the structural engineering knowledge and weather forecast data, it can be estimated the range of wind required for tornadoes to be present. In case the planet continues to warm, there will be an increase in the number of tornadoes since there will be a lot of thunderstorms experienced.
