The climate of Islamabad is a humid subtropical climate (Köppen climate classification, with five seasons: Winter (Nov–Feb), Spring (March–April), Summer (May–June), Rainy Monsoon (July–August) and Autumn (September–October).The hottest month is June, where average highs routinely exceed 38 °C ( °F). The wettest month is July, with heavy rainfall and evening thunderstorms. How Heavy is the Rain? Unlike the rain in many other countries, especially in the tropics, average hourly rainfall amounts in Ireland are quite low, ranging from 1 to 2mm. Short-term rates can of course be much higher: for example, an hourly total of 10mm is not uncommon and totals of 15 to 20mm in an hour may be expected to occur once in 5 years. Tomorrow weather is forecasted to be partly visibility is going to be around 10 km i.e. 6 miles and an atmospheric pressure of daytime temperature is going to reach 24 °c and the temperature is going to dip to 15 °c at will be dry with no precipitation and cloud covering 3% of the sky, the humidity will be around 32%.
Monthly rainfall dataset for Nasarawa State for 20 years () was obtained from the archives of Meteorological Observatory at the College of Agriculture, Lafia, Nasarawa State. Time series analysis of the monthly and annual rainfall values were used to illustrate the trend in the behavior of rainfall and in estimating seasonal variation.

WRRCTR No An Analysis of Four Showers with Rainfall Rates > mm/hr: Authors: Fullerton, Charles M. Wilson, S Kerry: LC Subject Headings: Rain and rainfall -- Hawaii. Date Issued: Jun Publisher: Water Resources Research Center, University of Hawaii at Manoa: Citation: Fullerton CM, Wilson SK.
Heavy rain: Greater than 4 mm per hour, but less than 8 mm per hour. Very heavy rain: Greater than 8 mm per hour. Slight shower: Less than 2 mm per hour. Moderate. Suppose that in a certain area the average rainfall in May is mm and that this amount is just sufficient to satisfy the water need of the crops during this month.
You may however find that, in this area, the rainfall in an exceptionally dry year is only 75 mm, while in a wet year the rainfall is mm.

Note the previous standard gave rainfall intensity figures in mm per hour per square meter for 2 minute storm event. To convert to mm/hr multiply the l/sec by e.g.
l/sec is equal to mm/hr or 75mm/hr is equal to l/sec. The standard also gives four categories of design rainfall intensity. Application rate (mm/hr) = Flow rate (l/hr; litres per hour) / AREA (m^2).
Therefore, as an example, if one nozzle outputs ml/min at a pressure of 7 PSI and there are 35 nozzles outputting an equal quantity of simulated rainfall (so ml * 35 = ml/min > ml/hr > l/hr) then the nozzles operating at 7PSI produce a fairly intense.
Average precipitation in depth (mm per year) | Data. Heavy rainfall is more than inches of rain per hour. Rainfall amount is described as the depth of water reaching the ground, typically in inches or millimeters (25 mm equals one inch).
An inch of rain is exactly that, water that is one inch deep. One inch of rainfall. Rainfall Measurement and Design Rainfall 14th April Manoranjan Muthusamy (Mano) a rainfall amount (mm) or intensity (mm/hr) can be worked out at high frequency (usually every 1, 2, 5 or 15 term rainfall data set, using a rainfall frequency analysis.
Re: Convert hourly rainfall(mm/hr) to rainfall rate (kg m-2 s-1). I am calculating rain rate for whole year though it didnt rain all the year. I took total rainfall for the year for a particular area, divided the rainfall value with area in sq Km and divided by X X 24 And the resultant values are plotted on graph and titled rain rate.
The analysis of the Calabar ten (10) years rainfall involved sorting of the rainfall amounts against durations of 15, 30, 45, 60, 90, and minutes and converting the rainfall amounts to intensity value in millimeter per hour (mm/hr).
The resulting rainfall intensity was File Size: KB. Rainfall (or precipitation) is measured as an absolute depth thus with a unit of length (i.e. mm, cm or inches depending on the chosen metric system) and refers to the net rainfall impacting earth surface and therefore does not account for evapora.
So, do you need volume or flow rate – you originally said volume. If you need an approximate flow rate, then 50mm/hr (or l/s/m2) can be assumed, as per para of Part H of the Building Regs.
disdrometer, the event from at UTC was analyzed. It is observed that for this specific time mention, the disdrometer record a Rainfall Rate of mm∙hr-1 and a radar reflectivity of dBZ.
A rainfall rate for the event of about 40 to 45 mm∙hr-1 was calculated. The reflectivity obtained from the Dual-Pol X-band. If mm is the day rainfall depth that can be expected on average in 8 years out of 10 during the first decade of January in Tunis, than is mm the 80% dependable annual rainfall for that decade.
As the rainfall amount increases, its probability of exceedance decreases. For Tunis, mm is the 50% and mm is the 20% dependable File Size: 2MB. All of them can have devastating rainfall accumulations of hundreds of millimetres happening at fast rates; rainfall rates of mm/hr are not uncommon.
In addition to the wind and rain, tropical cyclones can also produce high waves and damaging storm surge. They can even spawn tornadoes.

I got the data from tipping bucket rain gauge which produce an excel file contain time series, rainfall intensity and rainfall.
The rainfall here is constantly mm, so I can not use this data. • Rainfall Intensity (mm/hr) or rate of rainfall, i.e. the amount of heavy or intense rain that falls over a period of time of interest. High rainfall intensity indicates that it’s raining hard. • Rainfall Duration (how many hours it rained at that intensity) i.e.
the time of interest for water to potentially flood a “system, and. Violent rain — when the precipitation rate is > 50 mm ( in) per hour Euphemisms for a heavy or violent rain include gully washer, trash-mover and toad-strangler.
 The intensity can also be expressed by rainfall erosivity R-factor  or in terms of the rainfall time-structure n-index. rainfall stations island-wide with a sufficiently long period (since ) of continuous hourly rainfall records to enable the analysis of rainfall trends.
In the last thirty years, the average annual rainfall totals recorded at the 28 rainfall stations increased at a rate of mm per year (Figure 13).

In this paper, annual n-hourly maximum rainfall for different duration of ‘n’ such as 1-hour (hr), 2-hr, 3-hr, 6-hr, hr, hr, hr, hr and hr are extracted from hourly rainfall data recorded at Hissar and Kalingapatnam; and.

Along the peninsula, annual rainfall is higher on the Andaman coast (– mm yr − 1) than on the Gulf coast (– mm yr − 1). Tropical storms move across Thailand about 3–4 times per year between May and November.
The weather bureau categorises rainfall above mm in a hour period as “extremely heavy” while mm to mm of rain is considered ‘moderate’, mm to mm ‘heavy’, and.
In addition to these overall changes in precipitation rate, the changes to the precipitation processes also indicate a ‘shift’ in relative amounts of precipitation which can be attributed to different mechanisms – more specifically, a shift towards more local-scale convective rainfall and less non-convective (synoptic), large scale, rainfall.

There is a record of a cm rainfall event over 12 hours in Smethport, Pennsylvania on J It has also been claimed that cm of rain fell at Sahngdu in Inner Mongolia on July 3, in one hour; but that observation is poorly documented.
Moderate and heavy radar rainfall cases are screened very well in virtually all cases. Light radar rainfall cases ( mm hr-1) are the most difficult to screen. Precipitation Analysis Products and Applications. The near-real-time daily precipitation analysis has been used to develop a number of additional products and applications.

Type I and Type II rainfall distributions from TP 4 Figure 3. Annual maximum hour rainfall measured at Saipan IA, Capitol Hill, and Rota. 10 Figure 4. The mm/hr or in/hr is rainfall rate or intensity. So basically what it is saying is if the current rainfall rate were to occur over the span of an hour you would receive that amount of rain.
For example, if it were raining at.5in/hr and that continued for an hour you would receive.5 inches of rain. Rainfall is measured as a length, the normal unit here being millimetre. It is the depth to which water would accumulate if all the rainwater remained at the same place where it fell without flowing off or seeping into the ground.
