This file is a comprehensive set of notes on Climatology, covering the fundamental concepts of atmospheric changes, weather versus climate, elements of weather and climate, atmospheric structure, temperature distribution (horizontal and vertical), atmospheric pressure, condensation and precipitation mechanisms, types of winds, airmasses, weather fronts, jet streams, and global climatic classifications (such as Koppen’s system). It provides detailed explanations of climate processes, causes of climatic phenomena, and global patterns relevant for undergraduate geography study.
Time series: observations of well-defined data at regular intervals (weekly/monthly/yearly). Components: trend (long-term), cyclical (1-7 years), seasonal (yearly), irregular (random). Models: multiplicative (Y=T×C×S×I), additive (Y=T+C+S+I). Moving average smoothing for forecasting.
Sampling methods: probability (simple random, stratified, cluster, multistage) vs non-probability (purposive, convenience). Simple random: equal independent chance, requires population list. Stratified: heterogeneous subpopulations. Cluster: cost-effective. Multistage: widely spread populations.
