Explore the distinction between weather and climate, from day-to-day changes to long-term conditions. Learn about factors influencing weather patterns and how climate determines average atmospheric conditions. Discover how microclimates and hazardous weather events play a role in our environment.

Weather versus Climate • Weather comprises the day-to-day changes in observed atmospheric phenomena: • Temperature, Precipitation, Wind, Clouds • Climate is a description of the long-term and average atmospheric conditions at a site • Monthly Mean, Record Precipitation, Wind Rose
Weather versus Climate Weather Reports can be from every 15 minutes to once a day. KUNV 1254Z 30BKN 100OVC 7SM M01/M03/3411 Climate Reports describe the frequency of weather occurrences.
Role of Latitude length of daylight evaporation rates frequency within polar front zone vegetation type Role of Land continental vs maritime west side vs east side elevation altitude - biggest effect sources of moisture lakes, rivers, gulfs Weather versus Climate
Weather versus Climate • Frequency of Hazardous Weather • Tornadoes • Hail storms • Floods (Flash & River) • Damaging Winds • Lightning • Snowstorms • Ice Storms
Weather versus Climate • Microclimates • a separate climate within a larger climate zone • caused by smaller scale effects [natural and man-made] • slope of land • valley orientation • surrounding vegetation • soil type • nearby industry or population centers • water bodies (creeks, lakes, rivers)
Weather versus Climate • Climate is the way of measuring the average weather • seeks to describe elements in detail • uses statistical methods to explain • standard deviation • mean, median, mode • probability • return periods
