In the novel, Dracula by Bram Stoker, weather can be discussed in several ways. Think of how the weather affects the characters--not their actions, but the people themselves. Think how weather sets the atmosphere in the story such as the appearance of the castle, and the ghostly landscape which adds so much to the fear and madness expressed by the reactions of the people Jonathan meets. Imagine being in London in the graveyard and at Lucy's tomb if it were set in bright sunshine. Weather can affect mood and tone, the atmosphere in which the characters operate, and above all, the continual scraping of fear and anxiety which the ghostly, dark, dreary weather produces. If one hears odd noises in a brightly lit home, the effect is far different when the home is like the count's castle. Think of weather as another tool the writer can use to create the story and how it affects the people, the background, and the emotions of the reader. Then choose the elements you can use to show how the weather is important in your essay.
