1 00:00:01,000 --> 00:00:04,000 Weather and Climate 2 00:00:04,000 --> 00:00:08,000 An evening of heavy spring rains is on its way with gusty winds of moderate intensity. 3 00:00:08,000 --> 00:00:12,000 A cold front will bring down the maximum air temperatures, although the minimum will be the same. 4 00:00:12,000 --> 00:00:15,000 This can produce storms in the mountains. 5 00:00:30,000 --> 00:00:54,299 what is the weather how are clouds and storms formed the answer is found in the atmosphere 6 00:00:55,259 --> 00:00:57,159 Yes, here in the atmosphere. 7 00:00:57,979 --> 00:00:58,539 Atmosphere. 8 00:00:58,799 --> 00:00:59,539 Do you know what that is? 9 00:01:01,479 --> 00:01:04,540 The atmosphere is a layer of air surrounding the Earth. 10 00:01:05,659 --> 00:01:09,359 It allows all living things to breathe, regulates the planet's temperature, 11 00:01:09,540 --> 00:01:13,519 and protects it from particles and radiation from the sun and from outer space. 12 00:01:15,420 --> 00:01:19,480 All phenomena that determine weather conditions occur in the atmosphere. 13 00:01:20,379 --> 00:01:26,459 Clouds, rain, winds, storms, and hurricanes are formed in the atmosphere. 14 00:01:27,840 --> 00:01:29,019 But how do they occur? 15 00:01:29,719 --> 00:01:33,099 All atmospheric phenomena are originated by the sun. 16 00:01:33,859 --> 00:01:40,439 The sun influences all weather elements, such as temperature, humidity, and atmospheric pressure. 17 00:01:41,519 --> 00:01:44,239 Temperature is the amount of heat or cold in the atmosphere. 18 00:01:44,739 --> 00:01:47,760 It changes throughout the day, seasons, and regions 19 00:01:47,760 --> 00:01:50,980 according to the position of the Earth relative to the sun. 20 00:01:52,239 --> 00:01:56,879 Humidity is the amount of water in the atmosphere evaporated by the heat of the sun. 21 00:01:57,500 --> 00:01:58,939 Have you heard of the water cycle? 22 00:02:00,140 --> 00:02:01,400 Me, me, mine! 23 00:02:03,260 --> 00:02:08,300 Humidity and temperature in the atmosphere are responsible for the formation of clouds and rain. 24 00:02:09,740 --> 00:02:13,800 I'll tell you more about the water cycle in The Magic of Water. 25 00:02:14,240 --> 00:02:20,240 Atmospheric pressure is the weight of air over the Earth's surface. 26 00:02:20,240 --> 00:02:22,240 Air has weight. 27 00:02:22,240 --> 00:02:25,240 We live at the bottom of an ocean of air. 28 00:02:25,240 --> 00:02:28,240 The more air above us, the greater the pressure. 29 00:02:28,240 --> 00:02:31,240 Pressure changes with altitude and temperature. 30 00:02:31,240 --> 00:02:34,240 Warm air is lightweight and goes up, 31 00:02:34,240 --> 00:02:38,240 and is replaced by cold air, which is heavier and goes down. 32 00:02:38,240 --> 00:02:43,740 This movement of air masses produces winds. 33 00:02:45,740 --> 00:02:51,740 Temperature, humidity and atmospheric pressure are some of the weather elements, 34 00:02:51,740 --> 00:02:56,740 although there are more, such as cloud coverage, rainfall and wind. 35 00:02:56,740 --> 00:02:59,740 Weather and climate are not the same thing. 36 00:02:59,740 --> 00:03:04,740 Weather describes the conditions of the atmosphere at a particular time and place. 37 00:03:04,740 --> 00:03:07,740 Here and now, the weather is cloudy and rainy. 38 00:03:07,740 --> 00:03:09,740 What's the weather like where you live? 39 00:03:09,740 --> 00:03:20,979 Climate, however, describes the weather of a region over a longer period of time. 40 00:03:20,979 --> 00:03:25,900 The weather and other factors, such as landforms, the proximity of the sea, and the distance 41 00:03:25,900 --> 00:03:30,400 to the equator, all influence the climate. 42 00:03:30,400 --> 00:03:36,379 This creates different climates on Earth, with places as diverse as the jungle of Borneo, 43 00:03:36,379 --> 00:03:44,259 it rains for months, or the Atacama Desert, where 15 years can go without water. 44 00:03:44,259 --> 00:03:48,659 By learning about the climate of the region, Javier and Maliko are able to know what seeds 45 00:03:48,659 --> 00:03:53,000 to use and what time of the year to plant them. 46 00:03:53,000 --> 00:03:57,460 By knowing what the weather will be tomorrow, they can decide if today is okay to save some 47 00:03:57,460 --> 00:04:00,979 irrigation water. 48 00:04:00,979 --> 00:04:07,680 Can you think of other things for which it's important to know and predict the weather? 49 00:04:07,680 --> 00:04:09,539 The temperature is falling! 50 00:04:09,539 --> 00:04:12,259 Let's condense! 51 00:04:12,259 --> 00:04:14,139 Let's do it! 52 00:04:14,139 --> 00:04:22,540 Where will we fall this time?
