Test W-01
SCP-1149 Conditions: No wind, tested for one hour (baseline test)
Weather Conditions Prior to Test: Calm, winds east-southeast at approx. 5 kph, clear skies
Summary of events: Five events were recorded during this period. The first was the formation and dispersal of an abnormally small cumulonimbus cloud, accompanied by expected degrees of rain and lightning, which lasted for two minutes. The second was a pocket of fog, less than a kilometer in diameter, lasting for 45 seconds. The third was an area of intense heat, first noticed by the evaporation of sea water it caused. Temperatures were measured to reach 129° C (265° F) at the height of the event, which lasted 30 seconds. The fourth event was another pocket of fog, over a smaller area, accompanied by a temperature drop of approximately 10° C relative to the surrounding area, which lasted 3 minutes, 25 seconds. The final event was a small waterspout, forming without accompanying cloud cover. The cyclone lasted for 1 minute, 10 seconds, and remained in contact with the surface of the ocean for 30 seconds of that time. Cyclone wind speeds reached a peak of 112 kph (70 mph).

Researcher's note: For brevity's sake, following logs will only note newly observed phenomena.

Test W-02
SCP-1149 Conditions: 5 kph wind, tested for 62 minutes
Weather Conditions Prior to Test: Calm, winds east-southeast at approx. 5 kph, light cloud cover
Observed effects: Six events were recorded during this period. Of these, two consisted of new weather effects. The first of these lasted for 4 minutes, 10 seconds. A cloud of unusual density formed in a structure not previously observed on Earth. This cloud was accompanied by intense lightning strikes for the duration of its existence, and dropped rain, turning to snow, then back to rain. The second unique event occurred at the end of testing and lasted for 5 minutes. During this time, the temperature rapidly dropped in an area that grew to 0.25 km (0.16 mi) in diameter at the height of the event, with temperatures dropping to -80° C (-112° F). Water vapor in the air condensed and froze, creating a fog-like effect. The surface of the ocean also froze within this area of effect, to an estimated depth of 1.2 meters (4 feet).

Test W-04
SCP-1149 Conditions: 10 kph wind, blowing perpendicular to SCP-1149 (external fan approved for this test), tested for one hour
Weather Conditions Prior to Test: Winds southeast at approx. 15 kph, overcast, light rain
Observed effects: Four events were recorded during this period. No unique events occurred.

Researcher's note: This would seem to indicate that blowing perpendicularly doesn't have any effect. Though perhaps something will be observable at higher wind speeds.

Researcher's note: Test W-06, omitted for redundancy, further supports the above theory. Only air that travels along the length of SCP-1149 affects its effects.

Test W-07
SCP-1149 Conditions: 20 kph wind, tested for one hour
Weather Conditions Prior to Test: Winds south-southeast at approx. 5 kph, light cloud cover
Observed effects: Events were continuous during this period with many occurring simultaneously. Most were not unique, though three were of particular interest. The first was a highly dense, rapidly rotating cloud mass. After observing its odd color, further analysis indicated that it consisted of water mixed with hydrochloric acid, abnormal levels of carbon dioxide, and methane. The cloud mass was accompanied by frequent lightning and a partially formed cyclone. This event lasted for 9 minutes, 25 seconds. The second unique event was the repeated rapid formation and dispersal of an extremely low-pressure area, which was observed by the column of water that was quickly drawn up into it, then dropped. This process was repeated 6 times in a small area over the course of 1 minute, 10 seconds. The third unique event was a variation of a previously observed event. Over an area approximately 20 m (67 ft) in diameter, the air temperature rose and quickly peaked at 334° C (634° F), lasting for a total of 11 minutes. During this time, the surface of the ocean vaporized, creating a growing plume of steam. This event manifested near one of the observation vessels involved in testing, resulting in heat damage to part of the vessel's structure and varying degrees of burns to each of its crew. The event caused no fatalities and the vessel was able to retreat before damage became too great.

Researcher's note: Containment procedures updated. With events of this nature, we need a system in place to prevent people from entering the area.

Test W-17
SCP-1149 Conditions: ███ mph wind, tested for 27 minutes
Weather Conditions Prior to Test: Calm, winds east-northeast at approx. 10 kph, clear skies
Observed effects: Clouds immediately began to form, starting at the center of the cone of effect and spreading outward. Cloud composition was determined to be a condensed mixture of water with small amounts of hydrogen, helium, and ammonia. Lightning strikes were frequent, occurring nearly continuously starting at approximately 3 minutes. At approximately 5 minutes, the temperatures climbed above 90° C (194° Fahrenheit), causing the ocean within the cone of effect to begin vaporizing at an increased rate. Observation vessels retreated and were able to avoid damage for the duration of the test.

At approximately 15 minutes, cloud cover began condensing drastically and rotating rapidly, causing winds to reach speeds in excess of 400 kph (250 mph). At this point, the cone of effect had doubled in size due to indirect effects and the ocean continued to vaporize at its accelerated rate. By 27 minutes, the rotating storm had reached 240 kilometers (150 miles) in diameter with wind speeds recorded at ███ kph (███ mph). Small pockets of extremely high temperatures and pressure were observed, resulting in ionization of the air and bursts of light and sound similar to lightning. Satellite imagery reveals that at this point the storm bore a strong resemblance to [DATA EXPUNGED].

Testing was concluded at this point. The weather effects quickly dropped off in intensity, but did not fully disperse until over three hours later. The storm made land fall 20 minutes after the conclusion of testing, but by this point clouds mostly consisted of water and caused damage no worse than that of a typical tropical storm of mid-level intensity.

Researcher's note: Containment procedures updated. I think we can adequately test this thing without going over 30 kph. We could've been in trouble if those poisonous clouds made landfall.

Test E-01
SCP-1149 Conditions: 5 V DC, 0.5 A applied to wires, tested for 15 minutes
Weather Conditions Prior to Test: Calm, winds east-southeast at approx. 5 kph, light cloud cover
Observed effects: Effects similar to test W-07. Test terminated early.

Researcher's note: A direct current seems to simply amplify the effect. No need to prolong the test.

Test E-04
SCP-1149 Conditions: RS-232-like asynchronous serial communication transmission, transmitting the output of a looping C program, tested for one hour
Weather Conditions Prior to Test: Calm, winds northeast at approx. 10 kph, light cloud cover
Observed effects: Effects were especially erratic. Multiple events would occur at once and would quickly disperse, followed by calm periods. At times, events would be grouped together, and at others they would have no apparent grouping pattern. Single events occurred at multiple points during testing as well. None of the observed events were unique. When the timeline of observed behavior was compared to the timeline of the program's output, no further patterns could be deduced.

Test E-11
SCP-1149 Conditions: 1 V AC, 60 Hz, 1 A applied to wires, tested for 2 minutes, 21 seconds
Weather Conditions Prior to Test: Calm, winds east-southeast at approx. 10 mph, clear skies
Observed effects: Immediately after testing began, a single event started approximately 25 km (16 mi) directly west of SCP-1149. A high-pressure, high-temperature pocket formed, vaporizing the ocean beneath it. Much of the resulting steam was drawn into the pocket, which began to rotate, quickly picking up speed. The cyclone of water vapor soon reached a height of approximately 0.4 km (0.25 mi), becoming hotter and denser as it drew more water into itself. By this point, wind speeds had exceeded 150 kph (94 mph). After 1 minute, 30 seconds of testing, the cyclone began to emit light. After 1 minute, 45 seconds, the cyclone had grown to approximately 1 km (0.6 mi) high with an immediate area of effect of approximately 0.15 km (0.1 mi). Observation vessels nearest to the cyclone began to retreat due to the danger of the extreme light and heat. After 2 minutes, 21 seconds of testing, the cyclone was clearly visible with no magnification from the observational satellite. The heat and electromagnetic field of the cyclone were measurable at Site 37, causing multiple containment alarms to be triggered. The closest observation vessels to the cyclone began to suffer heat damage as they continued to retreat.

At this point, the electric signal was removed from SCP-1149, its wires were grounded, and the wind in its chamber was shut off. This resulted in the cyclone quickly expanding and returning to normal pressure, ejecting extremely hot water vapor and superheated liquid water out over a radius of over 8 km (5 mi), causing ██ injuries and █ fatalities to observational crew. The sudden expansion also caused a small tsunami, resulting in minor property damage along the coast, though it caused no civilian casualties.

Researcher's note: Containment procedures updated. We should discontinue this line of testing until we know more about what we're dealing with.
