![]() On Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms. The movement of mass ejected from the Sun is known as the solar wind.Ĭumulonimbus cloud surrounded by stratocumulus A star's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. However, the weather is not limited to planetary bodies. A famous landmark in the Solar System, Jupiter's Great Red Spot, is an anticyclonic storm known to have existed for at least 300 years. Studying how the weather works on other planets has been helpful in understanding how weather works on Earth. Human attempts to control the weather have occurred throughout history, and there is evidence that human activities such as agriculture and industry have modified weather patterns Earth's weather system is a chaotic system as a result, small changes to one part of the system can grow to have large effects on the system as a whole. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Higher altitudes are cooler than lower altitudes, as most atmospheric heating is due to contact with the Earth's surface while radiative losses to space are mostly constant. Surface temperature differences in turn cause pressure differences. Over thousands of years, changes in Earth's orbit can affect the amount and distribution of solar energy received by Earth, thus influencing long-term climate and global climate change. On Earth's surface, temperatures usually range ±40 ☌ (−40 ☏ to 104 ☏) annually. Because Earth's axis is tilted relative to its orbital plane (called the ecliptic), sunlight is incident at different angles at different times of the year. Weather systems in the middle latitudes, such as extratropical cyclones, are caused by instabilities of the jet streamflow. ![]() ![]() The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. Weather is driven by air pressure, temperature, and moisture differences between one place and another. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. These remaining roads are likely to take another 12 to 18 hours to clear due to large water catchment areas.Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.There are now just three roads that remain closed following yesterday’s heavy rain event, all due to flooding.Extended fine periods have seen flooding reduce rapidly across the district.Other roads affected in the Far North Road A full list of other roads affected is below.Maromākā-Tōwai Road and Matawaia-Maromākā Road, which are both within a large water catchment area, remain closed due to flooding.Overnight another two roads were closed due to slips bring the total closed to six.Despite increased periods of fine weather since Tuesday’s heavy rain event, our water-logged soils remain unstable, and we are seeing on-going impacts to our roading system.A remediation plan has been discussed, with repairs likely to commence today to enable reopening before Monday.įive roads are closed following Tuesday's weather event. Ōmanaia School Road, will be getting closed this morning, due to safety risks as a result of limited pavement widths.Four roads are closed following Tuesday's weather event.We will update this page when the situation changes. ![]() ![]() Road closures remain the same as this morning. Three roads are closed following Tuesday's weather event. The contractors re-opened this road on the weekend however they are still working on the road today so caution is required. Roadīelow are two images of Ōmanaia School Road. Contractors will continue to work on getting both roads re-opened. There are currently two roads still closed in the Far North District, Giles Road in Hōreke, which is a forestry route, and Smith Road in Herekino both due to underslips. Contractors were busy over the weekend focusing on immediate recovery activities, including clearance, removal of slip debris and vegetation. This will be the last update from the 9 May weather event. ![]()
