The weather determines what clothes to wear and the climate determines what clothes to buy.

Nothing on earth can escape the influence of weather and climate. In the process of absorbing solar energy, the temperature, humidity and pressure of the atmosphere are constantly changing, so weather is produced. That is to say, temperature, humidity and pressure are the controllers of atmospheric movement, so they are also the makers of weather. The weather is fully displayed in the sky above us, and every subtle change will affect us at any time. Weather refers to the change of meteorological elements in a specific place and in a short time. For example: the temperature in Dalian tomorrow, whether there is wind and rain, etc. This is different from the weather. Meteorology has no specific time and place, it is the general name of all weather phenomena in the atmosphere. Therefore, when we talk about the weather, we can only say, "It's a beautiful day today". Instead of saying, "it's a beautiful day." Simply put, climate refers to the multi-year average of weather in a certain area. For example, Dalian has four distinct seasons, with no heat in summer and no cold in winter. The main difference between climate and weather is that weather refers to short-term weather changes, while climate refers to describing the average situation of weather changes experienced by a region in a certain period according to the average value, extreme value and atmospheric circulation type of meteorological elements. So the two regions can be of the same climate type, and the weather can be different at any time. Climate is formed by the comprehensive action of atmospheric circulation, latitude, altitude and surface morphology (topography and its relationship with water). It can be seen that the shape and height of the terrain are affecting the climate, and the changeable terrain is the result of continuous weather carving for billions of years. If the weather determines what clothes you should wear, then the climate determines what clothes you should buy. Meteorologists observe today's atmospheric conditions to predict tomorrow's weather; Climatologists, on the other hand, focus on studying the laws of atmospheric movement in the past in order to find weather phenomena that are happening today and possible weather phenomena in the future. The atmosphere has no national boundaries, and the weather has no country. At present, the meteorological data of about 60,000 ground stations, 2,000 sounding balloons and 3,000 ocean newspapers and airplane newspapers can be obtained every day in the world. At the same time, various forms of meteorological satellites are also transmitting the evolution data of clouds and water vapor to the ground at any time. With such a huge amount of data, no one can guarantee its perfection and accuracy. It is these data that need to be processed by a supercomputer and calculated by different numerical models, and many weather forecast charts are obtained. According to these forecast charts, meteorologists make specific weather forecasts in combination with local weather characteristics and climate laws. For a long time, there are few scientific predictions that will not be laughed at. It is conceivable how difficult it is for people to try to accurately predict the weather.
