Main article: Timeline of meteorology Ancient forecasting įor millennia, people have tried to forecast the weather. Weather forecasting is a part of the economy, for example, in 2009, the US spent approximately $5.1 billion on weather forecasting, producing benefits estimated at six times as much. Since outdoor activities are severely curtailed by heavy rain, snow and wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. On an everyday basis, many use weather forecasts to determine what to wear on a given day. Temperature forecasts are used by utility companies to estimate demand over coming days. Forecasts based on temperature and precipitation are important to agriculture, and therefore to traders within commodity markets. Weather warnings are important forecasts because they are used to protect life and property. There is a vast variety of end uses to weather forecasts. The use of ensembles and model consensus help narrow the error and provide confidence level in the forecast. Hence, forecasts become less accurate as the difference between current time and the time for which the forecast is being made (the range of the forecast) increases. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the land, and the ocean, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric and related processes. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. Once calculated manually based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. People have attempted to predict the weather informally for millennia and formally since the 19th century. #WEATHER INDICATOR APP UPDATE#Weather tracker and forecast for your Mac's menu barĪs a downside, Weather Indicator allows you to refresh the weather information by hand, but does not seem to support automatic weather info update and it does not enable you to set custom refresh intervals.Īll things considered, Weather Indicator is a user-friendly and easy to use weather forecast utility for Macs, even though it does need a couple of extra features to provide you with all the features you would need from a weather monitoring app.Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. Here you can also view a 10-day weather forecast which will enable you to plan ahead for the entire week, as well as today's sunrise and sunset times.īesides allowing you to set Weather Indicator to start on login and configuring your location, the Preferences window can also be used to switch between metric and imperial measurement units, and to set the app to display weather information using colors. the current temperature, wind speed, and humidity. Weather Indicator also provides you with a status bar menu designed to give you detailed information regarding today's weather, i.e. Unfortunately, Weather Indicator failed to detect the location automatically, but, fortunately, the Mac's whereabouts can also be configured manually via the Preferences dialog. Upon launch, Weather Indicator asks you if you need it to start on login automatically, and will try to set the location automatically based on you Mac's location. Moreover, the Weather Indicator app will automatically add an item to your Mac's menu bar, making it very easy to monitor the current weather conditions by keeping an eye on its status bar icon. Unobtrusive and status bar-based weather tracking utility Software applications are among the simplest and less costly solutions, with Weather Indicator being a worthy candidate because of its simplicity and ease of use. Knowing the current weather conditions is very important if you are one who likes the outdoors and there are many ways of keeping a close eye on it.
