Worked examples questions - Weather Hazards

  ( Source )  Study the diagram above and state the two circulation cells that meet at latitudes of 30 degrees North and South of the Equator.         [ 2 marks ] State - express in clear terms  So first of all look for the two command words. Actually look at the diagram, identify where the 30 degree latitude lines. Latitude lines are the ones that go horizontal.  Then write down the two cells that meet at the 30 degree line of latitude. These are Hadley  and Ferrell cells . Note that there are two answers for two marks.  Too easy for you? How about this one? Explain how global atmospheric circulation contributes towards distinctive weather and climate patterns.                                     [ 4 marks ] Explain - set out purposes or reasons So, first of all you need to know something about the global atmospheric circulation - the Earth's atmosphere is constantly moving, transferring heat from one location to another via atmospheric circulation cells. each cell has distinc

The Queue - is it a micro pilgrimage?

Image
First of all, what is a pilgrimage? Pilgrimage - Wikipedia defines it as "...a journey, often into a unknown or foreign place, where a person goes in search of new or expanded meaning about their self, others, nature or a higher good, through the experience. It can lead to a personal transformation, after which the pilgrim returns to their daily life." We know that people are joining the queue to see the coffin of the Queen for many reasons and some have come from other countries.   ( Source ) The Queue or #thequeue is a temporary pilgrimage of between 6.9 miles between Southwark Park and Westminster Hall with a three mile zig-zagging park in the park. The location of importance in the hall is the body of Queen Elizabeth the Second.   ( Source )  It is interesting to note that the author of a paper " Pilgrims or Tourists ", the Christian Priest Frank Fahey states that "a pilgrim is always in danger of becoming a tourist" and vice versa. He identifies that

The Thunderstorms of September 2022

What is one? A thunderstorm or lightning or electrical storm is known for its lightning (and that come descend or ascend in various forms and colours) and its audible noise. If the thunder is quieter, it may be known as a thundershower.  (https://scijinks.gov/thunderstorms-video/thunderstorm_video_poster.png)    What causes one? NOAA (the National Oceanic and Atmospheric Administration) found in the USA states that a thunderstorm needs "three things - moisture, rising unstable air (air that keeps rising once given a nudge) and a lifting mechanism to provide the nudge".  (https://www.youtube.com/watch?v=A6cwPfYaBtA) The sun heats the ground that warms the air above the warmed ground. If the air is "forced" to rise where warm and and cold air or wet and dry air "bumps" into each other and this causes the warm air "to rise as long as as it weighs less and stays warmer than the air around it".  "As a storm rises into freezing air, different ty

Hot in the City

 This summer has certainly shown us some warm days.  There were three different heatwaves during the summer of 2022.      June with European temperatures ranging from 40 - 43 degrees Centigrade (or 104 - 109 degrees Fahrenheit).      Mid July where UK temperatures went over 40 degrees Centigrade (104 degrees Fahrenheit) for the first time. The UK released a red warning for the heat.      In August, parts of France and Spain had temperatures reach as high as 38 degrees Centigrade (100 degrees Fahrenheit).  (https://suindependent.com/wp-content/uploads/2022/07/Global-Heat-Wave-By-Jeff-Koterba.jpg)  Portugal had the highest temperature of 47.0 degrees Centigrade (116.6 degrees Fahrenheit) in Pinhão, Portugal.  Sadly with the heat comes heat stress and this leads to death.      Germany recorded the highest amount of heat related deaths with 8,318, Spain with 2,894, Portugal with 1,063 and the UK with 16.  Forest fires have been caused with the dry vegetation and the lack of water caused by
