In this lesson we will learn how to reduce by half or enlarge by doubling the grid of an original topographical map. We will locate and insert any obvious or more important details such as hilltops, drainage features, landmarks together with line features such as main roads and grid lines. We will also learn how to add the correct scale to the map.
In this lesson we will interpret a simple climate graph of the Maltese Islands showing the average monthly temperature and rainfall. We will also interpret the distribution of wind direction on a wind rose and recognise the difference between convectional and frontal rainfall as experienced in Malta.
In this lesson we will learn about the typical sequence of weather brought about by the passage of a mid-latitude depression. We will understand the meaning and sequence of the warm front, warm sector, cold front and occluded front and the typical weather associated with each. We will also learn how to recognise a depression on a weather chart and be able to forecast the weather for a particular locality shown on a weather chart that shows a mid-latitude depression.
