I've been counting who mentions which type of weather in their novels: Charlotte Bronte in Jane Eyre (see below); Emily Bronte in Wuthering Heights and Anne Bronte in The Tenant of Wildfell Hall.
Previously i presumed that Anne Bronte mentioned the weather the least - but it seems i'm wrong. She mentions the weather more than Emily does, however she uses more general descriptions: she uses phrases such as 'spendid morning', 'fine weather', loveliest days', 'splendid evening' more than Emily and Charlotte who are more distinct with their observations.
Anne Bronte mentions the sun and sunshine most frequently in The Tenant of Wildfell Hall.
Emily Bronte mentions the wind most frequently in Wuthering Heights, followed by the sun, then snow.
