Hays

The origins of the Hays of Erroll were investigated around 1954 by Wagner who presented evidence, based largely on heraldry, that the Scottish Hays were descended from de La Haye of La Haye-Hue in the Cotentin Peninsula of Normandy. That evidence begins with a seal used by David de Haya (Haia), the son of William II de Haya, on a charter around 1230. It shows the arms of argent three inescutcheons gules, i.e., a silver shield containing three smaller red shields, and are the same arms presently used by the Earl of Erroll. They bear no resemblance to those of the de La Haye of England, but they are the same as those used by Jean de La Haye-Hue in Normandy around 1368–1375.

The de La Haye of La Haye Hue can be traced back to the 12th century, that is, when William II de Haya was first known to be in Scotland. Wagner, therefore, concluded that the Hays of Erroll and the Hayes of La Haye were related. He also pointed out that the Hays were linked to the powerful Normandy family of Soulis Ranulf I de Soules in that La Haye-Hue, now called La Haye-Bellefond, is located just across the small Soules River from Soulles, the seat of that family. Secondly, the Soulis name, rare in England, and the more common Hay, are both found in the records of Dover castle in the early 13th century.</p> <p>A third point, which Wagner did not mention, is that William I de Haya married Juliana de Soulis and these two were the parents of William II de Haya.

Clouds

What are clouds?

A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.

How are clouds formed?

All air contains water, but near the ground, it is usually in the form of an invisible gas called water vapor. When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

Why are clouds white?

Since light travels as waves of different lengths, each color has its very own unique wavelength. Clouds are white because their water droplets or ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light.

Why do clouds turn gray?

Clouds are made up of tiny water droplets or ice crystals, usually a mixture of both. The water and ice scatter all light, making clouds appear white. If the clouds get thick enough or high enough all the light above does not make it through, hence the gray or dark look. Also, if there are lots of other clouds around, their shadow can add to the gray or multicolored gray appearance.

Why do clouds float?

A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that it's made of are warmer than the outside air around it, it floats!

How do clouds move?

Clouds move with the wind. High cirrus clouds are pushed along by the jet stream, sometimes traveling at more than 100 miles per hour. When clouds are part of a thunderstorm they usually travel at 30 to 40 mph.

Why do clouds form at different heights in the atmosphere?

The characteristics of clouds are dictated by the elements available, including the amount of water vapor, the temperatures at that height, the wind, and the interplay of other air masses.

How is fog formed?

There are many different types of fog, but fog is mostly formed when southerly winds bring warm, moist air into a region, possibly ending a cold outbreak. As the warm, moist air flows over much colder soil or snow, dense fog often forms. Warm, moist air is cooled from below as it flows over a colder surface. If the air is near saturation, moisture will condense out of the cooled air and form fog. With light winds, the fog near the ground can become thick and reduce visibilities to zero.
