The data spans 30 or more years. Meaning of driving rain. Climatology treats the same atmospheric processes as meteorology, but it seeks as well to identify the More than 1500 droplets of mass when Hippocrates published On Airs, Water, and Places.However, the field saw limited activity for almost 2000 years because we didn't have the tools to measure climate on a full scale or the ability to deliver news and predictions fast enough to make a difference. The study incorporates data for the period 1971 to 1995 and, from these data, the analysis reveals that severe WDR events are confined mainly to the southern United States and occur most frequently in the cold and transition seasons. Brussels, Belium: Royal Meteorological Institute of Belgium. Additionally, WDR is an agent for enhanced soil erosion and for dispersal of certain plant diseases. A method is proposed in the present paper, where wind-driven-rain intensities impinging on building faces are calculated taking into account all the relevant factors such as the interactions between wind, rain and building, and also the joint probability of occurrence of wind and rain. 1998Physical Geography, 19 (6): 445-462. The design and construction of durable, efficient walls requires consideration of the climate loads to which these building components will be exposed. It is observed that they are related by two factors, (a) the driving-rain coefficient and (b) the co-occurrence factor. Readers interested in learning more are encouraged to review other studies not covered here such as the work performed by the National Building Code of Canada that led to the development of the moisture index (Cornick and Dalgliesh, 2003). WDR intensity is estimated from a linear regression model that develops a relationship between rainfall on a horizontal surface and rainfall on a vertical surface. During the inter-monsoon season from March to May, the heating from the sun plays a strong role in driving precipitation. This model is used for the evaluation of the effects on the wind-driven rain intensity due to the various parameters. The terminal velocities for distilled water droplets falling through Exposure to WDR at these sites for baseline and future periods is calculated from semi-empirical models based on long-term hourly meteorological data using ISO 15927-3:2009. WDR intensity is estimated from a linear regression model that develops a relationship between rainfall on a horizontal surface and rainfall on a vertical surface. The Mann-Kendall and linear regression trend tests show decreasing trends in the Kiremt and the Belg extreme intensity and maximum, [1] Recently developed algorithms have shown the potential recovery of rainfall information from spaceborne dual-frequency altimeters. In this paper we compare TOPEX with near-simultaneous ground-based rain radars based at a number of locations, examining both the detection of rain and the quantitative values inferred. A comparison of IMD4 with 4 other existing daily gridded rainfall data sets of different spatial resolutions and time periods has also been discussed. Directional indices indicate that WDR occurs most often from easterly directions in locations in the southeast and central United States, while WDR is predominantly from the south along the West Coast. A nonhomogeneous hidden Markov model (NHMM) is used to stochastically simulate summer (June–August) daily precipitations in the middle and low reaches of the Yangtze River in Eastern China, with driving forcing from three global climate models (GCMs). When a wind is blowing, the drops are also carried along horizontally and with strong winds deflections of more than 45 degrees from the vertical can occur, even for large drops. Easter sunrise times. Appropriate corrections for nonuniform beam filling and drizzle fraction are harder to define globally. Rather than apply a bulk correction we investigate individual rain events to understand the cause of TOPEX's underestimation. Premature failures of building envelopes in the 1990s, notably in coastal areas of North America, point to problems with Moisture management by Exterior Wall Systems (MEWS)1. consecutive 5-day rains over eastern, southwestern and southern parts of Ethiopia whereas no trends are found in the remaining part of Ethiopia. Comparison with some, The study discusses development of a new daily gridded rainfall data set (IMD4) at a high spatial resolution (0.25° × 0.25°, latitude × longitude) covering a longer period of 110 years (1901-2010) over the Indian main land. Soil detachment and transport by wind- driven rain differs from that by rainless wind and from that by windless rainfall. Soil detachment from clods by rainfall did not differ among mulches of winter wheat, grain sorghum, and corn if the mulch quantity was expressed as percentage soil cover. The altimeter-only algorithm is found to flag false rain events in very low wind states (<3.8 m s(-1)); the application of an extra test, involving the liquid water path as sensed by the microwave radiometer, removes the spurious detections. Fernando Henriques of LNEC, Lisbon, considers the long‐term performance of buildings related to exposure conditions and presents the first year results of a study on driven rain. The method comprises the following steps: (a) using computational fluid dynamics method to calculate the flow pattern around a building, (b) raindrop trajectories in the flow field are obtained by solving the force equations, (c) obtain the probability of joint occurrence of wind and rain from the analysis of meteorological records, (d) rainfall intensities on building faces are computed as a function of return period by coupling (b) and (c). The occurrence of extreme precipitation events is now a serious concern in recent years in Japan. X Research source [8] X Research source The speed of stop-and-go traffic will be greatly reduced, meaning that if you or another car do actually collide, the damage will likely be minimal and not physically serious. History and climatology tell us that this is not the full story. This affects many hydrological studies such as hydrological forecasts, water erosion, determination of conditions for flash flood formation, determination of cropping conditions, etc.In this paper a nomograph is presented for the rain-gauge correction factor (Cgau), by which rainfall measured in a standard horizontal rain-gauge (Pgau) may be corrected to obtain the rainfall flux actually received on the inclined surface under study (Pact = Cgau × Pgau).
