बादलको प्राकृतिक सौन्दर्य
कपासी बादल, हवाईजहाज को झ्यालबाट लिइएको तस्विर

पृथ्वी अथवा अरु कुनै ग्रहको सतहमाथि वायुमण्डलमा देखिने पानीका वाष्पकण अथवा जमेको हिउँको स्फटिकको द्रव्यमानलाई बादल भनिन्छ । पृथ्वीको वायुमण्डलको बादलको अध्ययन नेफलोजी अथवा मौसम विज्ञानको भौतिकी शाखामा गरिन्छ।

Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Generally, precipitation will fall to the surface; an exception is virga which evaporates before reaching the surface. Clouds can show convective development, like cumulus, or be a layered sheet, such as stratus. Prefixes are used in connection with clouds: strato for low cumulus-category clouds that show some stratiform characteristics, alto for middle clouds, and cirro for high clouds. Whether or not a cloud is low, middle, or high level depends on how far above the ground its base forms. Some cloud types can form in the low or middle ranges depending on the moisture content of the air. Clouds have latin names due to the popular adaptation of Luke Howard's cloud categorization system, which began to spread in popularity during December १८०२. Synoptic surface weather observations use code numbers for the types of tropospheric cloud visible at each scheduled observation time based on the height and physical appearance of the clouds. While a majority of clouds form in the Earth's troposphere, there are occasions where clouds in the stratosphere and mesosphere are observed. Clouds have been observed on other planets and moons within the Solar System, but due to their different temperature characteristics, they are composed of other substances such as methane, ammonia, or sulfuric acid.

वायुमण्डल मा रहेको जलवाष्प को संघनन बाट बनेको जलकणहरु या हिमकण को विशाल राशि बादल भन्ने गरिन्छं ।
