Since there is no land mass in the vicinity, temperatures rarely drop below even in the winter.

Since the Northumberland Strait freezes in winter, the cables are designed to be protected from ice scouring and were copied from a Swedish design that was originally used to supply the island of Gotland in the Baltic Sea.

Since the winter conditions at the South Pole had never been measured, the station was built partially underground in order to protect it from the worst imaginable weather.

Since plague tends to abate in winter, some performances take place then ; Lord Strange's Men act a play called Titus — perhaps Shakespeare's Titus Andronicus — three times in January.

Since there are no automobile ferries currently operating on the lake, vehicles coming from the rest of Minnesota can reach the Angle without crossing the border only in winter.

Since it was winter the ground was frozen, making the digging of trenches impractical.

Since their foundation, " The Burgh ," have been based at James Y. Keanie Park ( named after the builder who donated the land The club was built upon ), but have much-delayed plans afoot to relocate within the next couple of years to a new ground at the more central Thomas Shanks Memorial Park less than one mile away, built in conjunction with the local council: the perpetually poor drainage at Keanie Park resulting in the regular postponement of home fixtures during the winter months has been a severe financial drain on the side.

Since 1936, the Town of New Windsor and the membership of the National Temple Hill Association have striven to ensure the preservation of this-the final winter encampment.

Since a green / blue tint signifies copious amounts of water, a strong updraft to support it, high winds from the storm raining out, and wet hail ; all elements that improve the chance for it to become severe, can all be inferred from this.

Since the winds in the higher latitudes predominantly blow west-to-east it can be seen that there is an easier route ( west-to-east ) and a harder route ( east-to-west ) when circumnavigating by sail ; this difficulty is magnified for square-rig vessels.

Since the SLDMB has a very small surface area above the ocean surface and a high underwater surface area, there is very little leeway in response to the direct forcing of winds and waves.

Since La Crescent is below the normal level of the rest of the area, the bluffside shields it from some of the harsh winds and tornadoes that other areas on consistently flat ground experience.

Since the man o ' war has no means of propulsion, it is moved by a combination of winds, currents, and tides.

Since most massive stars have luminosities far below the Eddington luminosity, however, their winds are mostly driven by the less intense line absorption.

Since the katabatic winds are descending, they tend to have a low relative humidity which desiccates the region.

Since the result, the sum of all angles, can add up to 0 or 2 * PI ( or multiples of 2 * PI ) only, it is sufficient to track through which quadrants the polygon winds, as it turns around the test point, which makes the winding number algorithm comparable in speed to counting the boundary crossings.

Since the hurricane bent the anemometer 30 degrees from the vertical, it is possible the winds at Brownsville were underestimated.

Since surface winds are the primary forcing mechanism in the spectral wave transport equation, ocean wave models use information produced by numerical weather prediction models as inputs to determine how much energy is transferred from the atmosphere into the layer at the surface of the ocean.

Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside.
