Notable Tropical Cyclones and Unusual Areas of Tropical Cyclone Formation
A flood is an overflow of an expanse of water that submerges land.[1] The EU Floods directive defines a flood as a temporary covering by water of land not normally covered by water.[2] In the sense of "flowing water", the word may also be applied to the inflow of the tide. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks levees, with the result that some of the water escapes its usual boundaries.[3] While the size of a lake or other body of water will vary with seasonal changes in precipitation and snow melt, it is not a significant flood unless such escapes of water endanger land areas used by man like a village, city or other inhabited area. Floods can also occur in rivers, when flow exceeds the capacity of the river channel, particularly at bends or meanders. Floods often cause damage to homes and businesses if they are placed in natural flood plains of rivers. While flood damage can be virtually eliminated by moving away from rivers and other bodies of water, since time out of mind, people have lived and worked by the water to seek sustenance and capitalize on the gains of cheap and easy travel and commerce by being near water. That humans continue to inhabit areas threatened by flood damage is evidence that the perceived value of living near the water exceeds the cost of repeated periodic flooding. The word "flood" comes from the Old English flod, a word common to Germanic languages (compare German Flut, Dutch vloed from the same root as is seen in flow, float; also compare with Latin fluctus, flumen). -

Presentation Sentences in Wikipedia: FSP Analysis; Diploma Thesis. Brno: Masaryk University, Faculty of Education, English Language and Literature Department, 2018. XX p. Supervisor: doc. Mgr. Martin Adam, Ph.D. Annotation The purpose of this thesis is an analysis of a corpus comprising of opening sentences of articles collected from the online encyclopaedia Wikipedia. Four different quality categories from Wikipedia were chosen, from the total amount of eight, to ensure gathering of a representative sample, for each category there are fifty sentences, the total amount of the sentences altogether is, therefore, two hundred. The sentences will be analysed according to the Firabsian theory of functional sentence perspective in order to discriminate differences both between the quality categories and also within the categories. -
On Tropical Cyclones
Frequently Asked Questions on Tropical Cyclones Frequently Asked Questions on Tropical Cyclones 1. What is a tropical cyclone? A tropical cyclone (TC) is a rotational low-pressure system in tropics when the central pressure falls by 5 to 6 hPa from the surrounding and maximum sustained wind speed reaches 34 knots (about 62 kmph). It is a vast violent whirl of 150 to 800 km, spiraling around a centre and progressing along the surface of the sea at a rate of 300 to 500 km a day. The word cyclone has been derived from Greek word ‘cyclos’ which means ‘coiling of a snake’. The word cyclone was coined by Heary Piddington who worked as a Rapporteur in Kolkata during British rule. The terms "hurricane" and "typhoon" are region specific names for a strong "tropical cyclone". Tropical cyclones are called “Hurricanes” over the Atlantic Ocean and “Typhoons” over the Pacific Ocean. 2. Why do ‘tropical cyclones' winds rotate counter-clockwise (clockwise) in the Northern (Southern) Hemisphere? The reason is that the earth's rotation sets up an apparent force (called the Coriolis force) that pulls the winds to the right in the Northern Hemisphere (and to the left in the Southern Hemisphere). So, when a low pressure starts to form over north of the equator, the surface winds will flow inward trying to fill in the low and will be deflected to the right and a counter-clockwise rotation will be initiated. The opposite (a deflection to the left and a clockwise rotation) will occur south of the equator. This Coriolis force is too tiny to effect rotation in, for example, water that is going down the drains of sinks and toilets. -

Upgrades to the M-PERC and PERC Models to Improve Short Term Tropical Cyclone Intensity Forecasts Derrick Herndon and Anthony Wimmers Cooperative Institute for Meteorological Satellite Studies University of Wisconsin- Madison James Kossin NOAA National Centers for Environmental Information (NCEI) Center for Weather and Climate, Asheville, North Carolina 74th Interdepartmental Hurricane Conference 2020 Lakeland, FL Feb 25-26 This work is sponsored by the NOAA Joint Hurricane Testbed Radar image of Hurricane Maria approaching Puerto Rico courtesy of Brian McNoldy Univ. of Miami, Rosenstiel School) ERC Onset Guidance: M-PERC Goal – Make incremental improvements to short range forecasts by giving forecasters a tool that objectively identifies Eyewall Replacement Cycle (ERC) onset. Microwave Probability of Eyewall Replacement (M-PERC) model Existing microwave-based model M-PERC was developed using Atlantic data - Baseline existing Atl-based model - Create Eastern/Central Pacific data - Create new model based on this basin-specific data - Test model in near real-time - Update web-based display to add SHIPS environment parameters (shear, sst, etc) ERC Onset Guidance: M-PERC TC Intensification Environmental Controls Internal Controls SSTs, wind shear, moisture Eye formation, convective bands Impact long range and short eyewall replacement cycles. Primarily range forecast impact short range intensity changes “The disparity between SHIPS forecasts and the observed intensity changes during ERCs is strongly suggestive that the typical environmental controls of intensity change, on which SHIPS is largely based, are temporarily countermanded while dynamic processes internal to the storm dominate the intensity evolution.”- Kossin ERC Onset Guidance: M-PERC In 2018 alone NHC mentioned ERCs 36 times in forecast discussions. -
Maui County Arborist Committee Meeting Minutes October 10, 2018
Maui County Arborist Committee Meeting Minutes October 10, 2018 1. Call to order at 1:39 pm by Alex Haller, Committee Chair, when it was determined that a quorum was present. The two previous meetings, August 8, 2018 and September 12, 2018 were cancelled due to Hurricane Hector and Tropical Storm Olivia. Cancellation of meetings are posted on the County website. Arine Bulkley inquired if the committee has to wait until the following month to meet again if a cancellation occurs. David Galazin, Corporation Counsel, informed the committee that they do have authority to have special meetings outside of regularly scheduled meetings dependent upon if members are able to meet to achieve quorum and if agenda is posted on time. 2. New Committee Business – a. Approval of minutes – Request by Alex Haller to replace “rode” with “road” in sentence 9 of subcommittee item 3d. Approval of the amended minutes for the committee meeting of July 11, 2018: motion to approve by Kimberly Thayer, seconded by Arine Bulkley and unanimously approved. b. Kula Park - Jacaranda Trees – Public testimony by Barbara Fernandez. The County has not addressed the glycine vines that are covering the Jacaranda trees in Kula Park. Stated that there is a neighborhood group willing to assist with the removal of the glycine. Also brought up replacement of a previously donated Rice Park tree that was removed about 2 years ago. Barbara stated that the family that donated the original tree would be open to donating another one. If committee wants to pursue that, she could contact the family. Alex asked for clarification of the location of the trees affected by the glycine. -
