Grade 12 Revision Mid Latitude Cyclones Geography

Hello leaners. hope you are doing well. I have prepared a small revision on mid latitude cyclones. the aim of the revision is to revisit geographical terms and concepts that we have learnt through when we were studying mid latitude cyclones, the revision will ensure that we accurately apply our knowledge during examinations and also help, to practice answering examination The question papers to be revised are Geography Paper 1 November 2024, and November 2023. Feel free to watch, comment and like the video. In the first question we are given a cross section of a mid-latitude cyclone. the cyclone is in the mature stage. the cold and warm fronts are clearly visible, the clouds, we have cumulonimbus clouds just above the cold front. cirrus and nimbombostrutus clouds above the warm front. we are given the direction of the mid latitude cyclone, from west to east. The first question, 1.3.1 in which general direction do mid latitude cyclones move? mid latitude cyclones move from West to east. Or you can say eastwards lets go to the next question 3.1.2 give a reason for your answer to question 3.1.1 mid latitude cyclones occur between 30–60-degree latitudes. it is in the same latitudes that the westerly winds blow in. the westerly winds blow the cyclone from west to east. so, they occur in the westerly wind belt. question 1.3.3 how does front A give rise to the formation of cumulonimbus clouds (4) if you check on the diagram front A, a Cold is very steep. this steepness will help the warm air, in the warm sector to lift very high, as the air rises high it cools and condenses there by forming the cumulonimbus clouds. so, the answers are. cold front will undercut warm air. steep gradient will cause rapid uplift of warm air. cooling and condensation occur. 2 marks for each point. lets move on to the last question of this paper. 1.3.4 in a paragraph of approximately 8 lines, explain the strategies that can be put in place to manage the negative environmental impact of the rainfall associated with mid latitude cyclones. i am going to discuss with you 4 points. I want you guys to poise the video for a while and type in the comment section at least a strategy that can be put in place to manage the environmental impact of rainfall associate with mid latitude cyclones. i have listed other point that we did not discuss about. you can pause the video and read. be free to add more that we did not discuss. feel free to share in the comment section. ok, let move on to the last question paper. November 2023. I will Start with the infographic the map shows the affected area. the area is found in the south of South Africa. we are given a graph showing the average rainfall from 15mm-40mm. then the cross section of a cold front. showing the clouds ahead and after the cold front. we are given also the direction of movement of the cold front. which is from west to east. lets go to the questions. question 1.3.1 the mid latitude cyclone mentioned in the extract is in the (initial/mature) stage. lets look at the cross section on the cyclone. the cross section is a good indicator we can use to check the stage of the cyclone. the cyclone has a well developed cold sector, we can see cumulonimbus clouds. this show that the cyclone is in the mature stage. the initial stage does not have all these features. the syclone will just he starting. 1.3.2 Give a reason for your answer to 1.3.1they are a number of reasons we can give 1, a well developed cold sector. wide spread rainfall. because the cyclone has developed the clouds can cover a wide area. a well developed cold and warm sector. presents of cumulonimbus clouds ahead of the cold front. 1.3.3 Why did rainfall mentioned in the extract spread from capetown, Mossel bay and nysna. mid latitude cyclones travel from west to east. so when the cyclone moves in- land it will start aproaching Capetown then move to to Mossel bay, and nysna. that is the order of the movement. from west to east. 1.3.4 refer to the graph and detemine the lowest and highest mm of rainfall recorded in the western cape over 36 hours.the lowest rainfall recorded is 15 and the highest is 40mm. 1.3.5 With reference to the cross section, explain how a well developed cold front results in heavy rain over the western cape. a well developed Cold front contributes to heavy rains by forcing warm, moist air rapidly upward as the cooler, denser air mass pushes underneath it, causing the rising air to cool, condense, and form clouds that can produce significant precipitation 1.3.6 How will the heavy rainfall negatively affect the physical (natural) environment in and around Western cape.
