Happy New Year from Columbia Weather Systems! |
New Solar Radiation Sensor
|

Our new visibility sensor is now available for use with either Capricorn or Orion weather stations equipped with the Weather Microserver. It measures atmospheric visibility (meteorological optical range) by determining the amount of light scattered by particles (smoke, dust, haze, fog, rain, & snow) in the air that pass through the optical sample volume. A 42-degree forward scatter angle is used to ensure performance over a wide range of particle sizes. The sensor is made from anodized aluminum and rugged, UVresistant fiberglass enclosures rated to IP66. Based on the proven field experience of the NWS and FAA, the sensor uses a “look down” geometry to reduce window contamination and clogging from blowing snow. All power and signal lines to the sensor are protected with surge and EMI filtering to help ensure uninterrupted service. Installation and maintenance are simple – a mounting flange located on the bottom of the main enclosure box mates with a user-supplied 1-1/2 inch IPS mounting pipe. Power and signal cables are installed through waterproof cable glands on the bottom of the main enclosure box to terminal boards for simple but reliable connections. Annual field calibration is recommended using a calibration fixture that is included with the sensor. Options include heaters for extreme snowy environments and a photometer for aviation applications. |

Capricorn 2000 Meets Hurricane Ike, continued
Hurricane Winds The winds started increasing late Friday evening September 12, when the outer bands of the storm system reached the beaches of Galveston. The eye of Hurricane Ike made landfall on the eastern side of Galveston Island early Saturday morning September 13. At midnight a quick check on the weather console revealed wind velocities increasing to the 20mph range with peak gusts exceeding 40 mph. The sensors for my station are mounted approximately 5 ft above the roof peak, which places them about 45 feet above the ground. My house is heavily surrounded by trees, so the actual wind velocities are somewhat skewed. The eye of Hurricane Ike passed about 30 miles to the east of my home about 7 a.m. Saturday. I live in the extreme Northwest portion of Houston, about 70 miles as the crow flies from the Gulf Coast. Needless to say I did not sleep at all that evening. My battery powered radio took a back seat for weather information as I continually checked my station’s wind velocity, peak gusts, rainfall rates and accumulation. I noticed that the gust indicator on the console would measure a peak gust about 2-3 seconds before I felt the house windows shudder. Steady wind speeds throughout the early and mid-morning averaged about 55-60 m.p.h with gusts reaching 75 m.p.h. These gusts would come in waves as the bands from the storm traversed over my location. I never did witness the calm of eye, for the winds never decreased until Ike completely passed through Houston. Throughout the night you could hear the tree limbs snapping with an occasional bang of a line transformer exploding in the distance. My Dachshund Bosco was a good indicator of trees snapping, for he would “woof” every time a tree or limb broke. Needless to say, he was “woofing” continually throughout the night. Rainfall and Flooding Living on the edge of the creek I was also concerned about rainfall. There is no concern of my property flooding until the daily accumulated rain reaches the 10-inch level. Rainfall rates during Ike averaged 3-4 inches per hour, though due to bands of precipitation Ike produced, the heavy downpours only lasted 20 minutes or so, with 30-45 minute intervals. This duration of these downpours drastically changed when the backside of the storm reached my location. By 10:00 the following morning the total rainfall was only 5.5 inches. The winds began subsiding (gusts of 40 mph) by 9 a.m. and I mistakenly thought the worst was over. As the final bands of precipitation came over the house the rain rate increased to about 5 inches an hour. That’s a lot of water! This rate lasted for little over an hour dumping another 6 inches on my property. The total rainfall in a 12-hour period was 11.5 inches. The storm finally passed around noon Saturday. About 6 hours later as the creek rose there was about 18 inches of water on my property. Fortunately my home sits 5 ½ ft off the ground, so the house was high and dry. As the water rose later that afternoon, my wife and I decided to leave and spend the night at a friend’s house. The water quickly receded that evening and we returned the following morning to begin the cleanup which seemed to last for weeks.
The damage to my house was minimal, a few minor roof leaks and some thermal seals leaking in my windows. The most damage inflicted by Ike was from falling trees, the flooding was minimal. Severe building damage, such as buildings collapsing, were rarities. In fact there were very few blown down billboards. Tree damage was the number one type of damage, many falling on homes. On my property fortunately I did not lose a single tree but the falling tree limbs were extensive. It took five workers three days to clean the two acres I live on. There was over 180 yards of tree debris removed from my property. (For perspective, the largest garbage dumpster you see at construction sites is only 40 yards.) While I was responsible in the cleanup my property, FEMA actually removed the debris, which was placed in the street, in front of my house. Local neighbors were not as lucky as I. Many had fences knocked down and a few had trees falling on their houses, the worst one, a tree falling squarely on his mother-in-law living quarter’s roof. Luckily no one was injured. FEMA Response Retrospectively I think FEMA learned how NOT to handle a disaster with Hurricanes Katrina and Rita. Overall did an excellent job responding Hurricane Ike here in Texas. There were power line repair crews working on the grid just days after storm. was no looting, nor any chaos throughout city. My debris picked up only 2 ½ weeks Pod sites quickly established city supplying people food ice. FEMA roof repair crews were in my neighborhood the following Tuesday. Hurricane Ike is still concern of mine, since am dealing insurance company for some minor claims. The adjuster stated that he is here in Houston for two to three months while he helps my insurance company handle the 60,000+ claims!
Living in Houston, Texas for the past 30 years, hurricanes and severe weather are a major concern to me both on a personal and professional level, more so in recent years, for my home backs up to a major watershed creek in the county. Hurricane Ike was the second hurricane I experienced where the track of its eye passed in close proximity to my home, the first being Hurricane Alicia back in 1983. In June of 2001, Tropical Depression Alison stalled over Houston and dropped over 18 inches of water in a 24-hour period. Unfortunately I was out of town at the time and did not know exactly the weather conditions at my home, especially the rainfall rates and accumulation. I decided after Allison that it was time to invest in a professional-grade weather station. I could then monitor, in real time via the internet, the actual weather conditions at my home, both current and accumulated. This information would not only be used for my personal needs but also in my profession as a corporate pilot. I regularly read Weatherwise magazine and the Columbia Weather advert caught my attention, especially the touch screen console interface. No other weather equipment manufacturer at the time had a touch screen interface. A quick call to Columbia Weather Systems resulted in a long conversation with its president, Nader Khoury. I was impressed with Nader’s technical knowledge and his attention to customer service, which is very important to me as a customer. I ordered a system, and a few weeks later, my system arrived and was installed in my home. Since then it has become a permanent fixture in my study. The touch screen console sits on my desk and is monitored many times throughout out the day. My weather station also has a full time connection to the Internet and is on the Weather Underground Web Site with the Rapid Fire option. Rapid Fire polls my station every 5 minutes and logs the data. It gives me access (via Internet) to the actual “real time weather conditions and trends” at my home, that I can easily check, even on my Blackberry. It was 25 years between Hurricane Alicia and Hurricane Ike. Hopefully it will be another 25 years before Houston sees another major hurricane! --Author and weather enthusiast Tom Rum is senior captain for Cooper Industries. |
