A saturated atmosphere is any atmosphere where … Warm air is less dense than cold air. The weather of a particular region keeps changing everyday depending on temperature, rainfall and wind conditions but the climate would show the long term behaviour of the weather in that region. So, weather is similar to your mood on a day and climate is like your overall personality. rainfall synonyms, rainfall pronunciation, rainfall translation, English dictionary definition of rainfall. This is climate. Average annual rainfall exceeds 200cm to 250cm. about 70 mm/month, over oceans and land together. Precipitation is heaviest near the ITCZ and in areas where monsoon winds come from … Moving a little to the south specifically at the middle of the country the weather becomes more moderate, and there is some rain at autumn. Precipitation of Equatorial Climate: Equatorial regions receive rainfall throughout the year and thus there is no dry season. What Is Frontal Rainfall? In the Dry Valleys of Antarctica (above), average annual temperature is -20°C (-4°F) and precipitation can be as low as 10 millimeters (0.4 inches) a year. This causes the air to expand and rise. Rainfall is of three different types namely – Orographic, Frontal (Cyclonic rainfall), and Convectional rainfall.. Orographic or Relief Rainfall and its Features. There are 3 main types of rainfall: relief, frontal and convectional. South Africa is a relatively dry country, with an average annual rainfall of about 464 mm. 2. These deserts are created by cold winds tumbling off the Antarctic plateau and roaring down the valleys. Relief rainfall occurs very frequently near mountains beside the sea because of the ascent of air forced by the mountain barrier. When the two air masses meet, warm air is forced over the cold air, because it is less dense. Climate (from Ancient Greek klima, meaning inclination) is commonly defined as the weather averaged over a long period. This causes the air to cool and the moisture in the air condenses and rain falls. Climate. A subtropical location, moderated by ocean on three sides of the country and the altitude of the interior plateau, account for the warm temperate conditions. Convectional rainfall When the land warms up, it heats the air above it. Frontal rainfall is a type of condensation that occurs when a cold front meets a warm front. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. As air rises it cools it cannot hold as much moisture as it could when it was warmer. One can define it as any aqueous deposit in liquid or solid form that develops in a saturated atmosphere and falls to the ground generally from clouds. n. 1. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.
