It is very important to know where the radar is located as that is your reference point for proper interpolation of the wind's motion.īase Velocity images provides a picture of the basic wind field from the ½° elevation scan. In all velocity images, red colors indicate wind moving away from the radar with green colors representing wind moving toward the radar. This is called radial velocity as it is the component of the target's motion that is along the direction of the radar beam. However, the only motion it can 'see' is either directly toward or away from the radar. One of the best features on the 88d Doppler radar is its ability to detect motion.

View a sample composite reflectivity image (scroll down). It is used to reveal the highest reflectivity in all echoes. It is composed of the greatest echo intensity (reflectivity) from any elevation angle seen from the radar. View a sample base reflectivity image.Ĭomposite Reflectivity images utilize all elevation scans during each volume scan to create the image. This image is available upon completion of the ½° elevation scan during each volume scan.

There are two versions of Base Reflectivity image the short range version which extends out to 124 nm (about 143 miles) and the long range version which extends out to 248 nm (about 286 miles). Taken from the lowest (½° elevation) slice, it is the primary image used to 'see what's out there'.

There are two types available on the web Base (or ½° elevation) reflectivity and Composite reflectivity.īase Reflectivity is the default image. A hint of that complexity can be seen in the accompanying 2D animation of one of the simplest possible regular 4D objects, the tesseract, which is analogous to the 3D cube.These images are just as they sound as they paint a picture of the weather from the energy reflected back to the radar.

It is only when such locations are linked together into more complicated shapes that the full richness and geometric complexity of higher-dimensional spaces emerge. Single locations in Euclidean 4D space can be given as vectors or n-tuples, i.e., as ordered lists of numbers such as ( x, y, z, w). Einstein's concept of spacetime has a Minkowski structure based on a non-Euclidean geometry with three spatial dimensions and one temporal dimension, rather than the four symmetric spatial dimensions of Schläfli's Euclidean 4D space. Einstein's theory of relativity is formulated in 4D space, although not in a Euclidean 4D space. Large parts of these topics could not exist in their current forms without using such spaces. Higher-dimensional spaces (greater than three) have since become one of the foundations for formally expressing modern mathematics and physics. The eight lines connecting the vertices of the two cubes in this case represent a single direction in the 'unseen' fourth dimension. This can be seen in the accompanying animation whenever it shows a smaller inner cube inside a larger outer cube. The simplest form of Hinton's method is to draw two ordinary 3D cubes in 2D space, one encompassing the other, separated by an 'unseen' distance, and then draw lines between their equivalent vertices. In 1880 Charles Howard Hinton popularized it in an essay, ' What is the Fourth Dimension?', in which he explained the concept of a ' four-dimensional cube' with a step-by-step generalization of the properties of lines, squares, and cubes. Schläfli's work received little attention during his lifetime and was published only posthumously, in 1901, but meanwhile the fourth Euclidean dimension was rediscovered by others. The general concept of Euclidean space with any number of dimensions was fully developed by the Swiss mathematician Ludwig Schläfli before 1853. published in 1754, but the mathematics of more than three dimensions only emerged in the 19th century. The idea of adding a fourth dimension appears in Jean le Rond d'Alembert's 'Dimensions'.
