Only seasonal warmings and coolings and changes in precipitation patterns have bigger effects. 4. Precipitation patterns follow the classic Mediterranean range, from October to April.5. The federal scientists set out to measure changes in temperature and precipitation patterns . 6. :Climate change = Long term changes in temperature and precipitation patterns . 7. Increasing atmospheric emissions also plays an integral role in precipitation patterns . 8. The cycle is one of the dominant forces shaping year-to-year storm and precipitation patterns . 9. The K�ppen climate classification system uses seasonal precipitation patterns as part of its climate definitions. 10. This is due to the diversity of climate and the precipitation patterns in the country.
