When we are updating variables that are impacted by interrupt handler routines we need to disable interrupts. Here we check if the tip count has increased. If so we then recalculate the rainfall total. Once done we reactive the interrupt handlers. In this sketch we have activated the data transmit led which we will use when we are transmitting data to the web server.

We have mounted the power and transmit led so they are visible outside the controller box. It's useful for debugging and it annoys the rats at night time.

In this sketch we just toggle the led every 2 seconds when we output data to the console. The sketch displays data from all of the sensors we have connected so far. To simulate rain we tipped some water from a Rain Weather on the sensor.

Observation: The Hydreon sensor is not as accurate as a tipping bucket rain gauge. It tends to read high in comparison. Weather forecast RainViewer provides an hourly forecast for the next 48 hours and a general for the next 14 days.

The wet season is a time when air quality improves, [55] freshwater quality improves, [56] [57] and vegetation grows significantly. Tropical cyclonesa source of very heavy rainfall, consist of large air masses several hundred miles across with low pressure at the centre and with winds blowing inward towards the centre in either a clockwise direction southern hemisphere or counter clockwise northern hemisphere.

The fine particulate matter produced by car exhaust and other human sources of pollution forms cloud condensation nucleileads to the production of clouds and increases the likelihood of rain. As commuters and commercial traffic cause pollution to build up over the course of the week, the likelihood of rain increases: it peaks by Saturday, after five days of weekday pollution has been built up.

This extra heat leads to greater upward motion, which can induce additional shower and thunderstorm activity. Increasing temperatures tend to increase evaporation which can lead to more precipitation. Globally there has been no statistically significant overall trend in precipitation over the past century, although trends have varied widely by region and over time.

Eastern portions of North and South America, northern Europe, and northern and central Asia have become wetter. The Sahel, the Mediterranean, southern Africa and parts of southern Asia have become drier.

There has been an increase in the number of heavy precipitation events over many areas during the past century, as well as an increase since the s in the prevalence of droughts—especially in the tropics and subtropics.

Over the contiguous United States, total annual precipitation increased at an average rate of 6. Analysis of 65 years of United States of America rainfall records show the lower 48 states have an increase in heavy downpours since The largest increases Rain Weather in the Northeast and Midwest, which in the past decade, have seen 31 and 16 percent more heavy downpours compared to the s. Heavy downpour in the analysis are the days where total precipitation exceeded the top one percent of all rain and snow days during the years — The most successful attempts at influencing weather involve cloud seedingwhich include techniques used to increase winter precipitation over mountains and suppress hail.

Rainbands are cloud and precipitation areas which are significantly elongated. Rainbands can be stratiform or convective[68] and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure.

Rainbands Rain Weather near and ahead of cold fronts can be squall lines which are able to produce tornadoes. If sea breeze rainbands become active enough just ahead of a cold front, they can mask the location of the cold front itself. Once a cyclone occludes an occluded front a trough of warm air aloft will be caused by strong southerly winds on its eastern periphery rotating aloft around its northeast, and ultimately northwestern, periphery also termed the warm conveyor beltforcing a surface trough to continue into the cold sector on a similar curve to the occluded front.

The front creates the portion of an occluded cyclone known as its comma headdue to the comma -like shape of the mid-tropospheric cloudiness that accompanies the feature. It can also be the focus of locally heavy precipitation, with thunderstorms possible if the atmosphere along the front is unstable enough for convection.

Downwind of islands, bands of showers and thunderstorms can develop due to low level wind convergence downwind of the island edges. Offshore Californiathis has been noted in the wake of cold fronts. Rainbands within tropical cyclones are curved in orientation. Tropical cyclone rainbands contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm.

The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. The phrase acid rain was first used by Scottish chemist Robert Augus Smith in Sulfuric acid is derived from natural sources such as volcanoes, and wetlands sulfate reducing bacteria ; and anthropogenic sources such as the combustion of fossil fuels, and mining where H 2 S is present.

Nitric acid is produced by natural sources such as lightning, soil bacteria, and natural fires; while also produced anthropogenically by the combustion of fossil fuels and from power plants.

In the past 20 years the concentrations of nitric and sulfuric acid has decreased in presence of rainwater, which may be due to the significant increase Rain Weather ammonium most likely as ammonia from livestock productionwhich acts as a buffer in acid rain and raises the pH. Specifically, the primary types are A, tropical; B, dry; C, mild mid-latitude; D, cold mid-latitude; and E, polar. The five primary classifications can be further divided into secondary classifications such as rain forestmonsoontropical savannahumid subtropicalhumid continentaloceanic climateMediterranean climatesteppesubarctic climatetundrapolar ice capand desert.

Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1, and 2, mm 69 and 79 in. They are widespread on Africa, and are also found in India, the northern parts of South America, Malaysiaand Australia. Most summer rainfall occurs during thunderstorms and from occasional tropical cyclones. An oceanic or maritime climate is typically found along the west coasts at the middle latitudes of all the world's continents, bordering cool oceans, as well as southeastern Australia, and is accompanied by plentiful precipitation year-round.

The climate is characterized by hot, dry summers and cool, wet winters. Rain is measured in units of length per unit time, typically in millimeters per hour, [91] or in countries where imperial units are more common, inches per hour.

The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in mm 4-in plastic and mm 8-in metal varieties.

Plastic gauges have markings on the inner cylinder down to 0. After the inner cylinder is filled, the amount inside it is discarded, then filled with the remaining rainfall in the outer cylinder until all the fluid in the outer cylinder is gone, adding to the overall total until the outer cylinder is empty. Any of the above rain gauges can be made at home, with enough know-how.

One of the main uses of weather radar is to be able to assess the amount of precipitations fallen over large basins for hydrological purposes. Radar-derived rainfall estimates complement surface station data which can be used for calibration. To produce radar accumulations, rain rates over a point are estimated by using the value of reflectivity data at individual grid points. A radar equation is then used, which is. Satellite derived rainfall estimates use passive microwave instruments aboard polar orbiting as well as geostationary weather satellites to indirectly measure rainfall rates.

Rainfall intensity is classified according to the rate of precipitation, which depends on the considered time. Euphemisms for a heavy or violent rain include gully washer, trash-mover and toad-strangler.

The likelihood or probability of an event with a specified intensity and duration, is called the return period or frequency. As with all probabilistic events, it is possible, though improbable, to have multiple "1 in Year Storms" in a single year. The Quantitative Precipitation Forecast abbreviated QPF is the expected amount of liquid precipitation accumulated over a specified time period over a specified area.

Precipitation forecasts tend to be bound by synoptic hours such as, and GMT. Terrain is considered in QPFs by use of topography or based upon climatological precipitation patterns from observations with fine detail.

The forecasts can be verified through use of rain gauge measurements, weather radar estimates, or a combination of both. Various skill scores can be determined to measure the value of the rainfall forecast. Precipitation, especially rain, has a dramatic effect on agriculture.

All plants need at least some water to survive, therefore rain being the most effective means of watering is important to agriculture. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops. Drought can kill crops and increase erosion, [] while overly wet weather can cause harmful fungus growth. For example, certain cacti require small amounts of water, [] while tropical plants may need up to hundreds of inches of rain per year to survive.

In areas with wet and dry seasons, soil nutrients diminish and erosion increases during the wet season. The previous dry season leads to food shortages into the wet season, as the crops have yet to mature. Cultural attitudes towards rain differ across the world.

In temperate climatespeople tend to be more stressed when the weather is unstable or cloudy, with its impact greater on men than women. In dry places, such as India, [] or during periods of drought[] rain lifts people's moods. In Botswanathe Setswana word for rain, pulais used as the name of the national currencyin recognition of the economic importance of rain in its country, since it has a desert climate.

The source of this scent is petrichoran oil produced by plants, then absorbed by rocks and soil, and later released into the air during rainfall. Rain holds an important religious significance in many cultures. Approximatelykm 3cu mi of water falls as precipitation each year across the globe withkm 3 95, cu mi of it over the oceans.

Deserts are defined as areas with an average annual precipitation of less than mm 10 in per year, [] [] or as areas where more water is lost by evapotranspiration than falls as precipitation. The northern half of Africa is occupied by the world's most extensive hot, dry region, the Sahara Desert.

Some deserts are also occupying much of southern Africa : the Namib and the Kalahari. Across Asia, a large annual rainfall minimum, composed primarily of deserts, stretches from the Gobi Desert in Mongolia west-southwest through western Pakistan Balochistan and Iran into the Arabian Desert in Saudi Arabia.

Most of Australia is semi-arid or desert, [] making it the world's driest inhabited continent. Since rain only falls as liquid, it rarely falls when surface temperatures are below freezing, unless there is a layer of warm air aloft, in which case it becomes freezing rain. Due to the entire atmosphere being below freezing most of the time, very cold climates see very little rainfall and are often known as polar deserts. A common biome in this area is the tundra which has a short summer thaw and a long frozen winter.

Ice caps see no rain at all, making Antarctica the world's driest continent. Rainforests are areas of the world with very high rainfall. Both tropical and temperate rainforests exist. Tropical rainforests occupy a large band of the planet mostly along the equator. Most temperate rainforests are located on mountainous west coasts between 45 and 55 degrees latitude, but they are often found in other areas.

The equatorial region near the Intertropical Convergence Zone ITCZor monsoon trough, is the wettest portion of the world's continents. Annually, the rain belt within the tropics marches northward by August, then moves back southward into the Southern Hemisphere by February and March. Its poleward progression is accelerated by the onset of the summer monsoon which is characterized by the development of lower air pressure a thermal low over the warmest part of Asia.

Westerly flow from the mild north Atlantic leads to wetness across western Europe, in particular Ireland and the United Kingdom, where the western coasts can receive between 1, mm 39 inat sea level and 2, mm 98 inon the mountains of rain per year. BergenNorway is one of the more famous European rain-cities with its yearly precipitation of 2, mm 89 in on average.

During the fall, winter, and spring, Pacific storm systems bring most of Hawaii and the western United States much of their precipitation. There is also evidence that global warming is leading to increased precipitation to the eastern portions of North America, while droughts are becoming more frequent in the tropics and subtropics.

Cherrapunjisituated on the southern slopes of the Eastern Himalaya in ShillongIndia is the confirmed wettest place on Earth, with an average annual rainfall of 11, mm in.

The highest recorded rainfall in a single year was 22, mm The year average at nearby MawsynramMeghalayaIndia is 11, mm Its summit is considered one of the rainiest spots on earth, with a reported days of rain per year. This amount is more than what falls in many cities in a year's time. Rainfalls of diamonds have been suggested to occur on the gas giant planetsJupiter and Saturn[] as well as on the ice giant planetsUranus and Neptune.
